The Momentum and Mass of A Photon in A Medium- Classical Approach

Thu, 09 Mar 2017 18:18:55 GMT

title: The Momentum and Mass of A Photon in A Medium- Classical Approach abstract: The corpuscular nature of light including the momentum and mass of a photon in a medium has been of extensive interest and controversy for hundreds of years. The elegant analogy between classical mechanics and optics done by E. Fermi has been extended in this work, and it is shown that for a quasi-monochromatic light (of center frequency ν) propagating in a medium of refractive index n, the photon momentum p= nhν/c, the photon mass m= nn'hν/c², where n' is the group index, and m= n²hν/c² for a monochromatic light, which can also be obtained through the ray equation.

Landau quantization in monolayer GaAs

Thu, 12 Jan 2017 18:11:29 GMT

title: Landau quantization in monolayer GaAs abstract: Landau quantization in monolayer GaAs1 HSIEN-CHING CHUNG2, National Kaohsiung Normal University, CHING-HONG HO, CHENG-PENG CHANG, Tainan University of Technology, CHUN-NAN CHEN, Tamkang University, CHIH-WEI CHIU, National Kaohsiung Normal University, MING-FA LIN, National Cheng Kung University — In the past decade, the discovery of graphene has opened the possibility of two-dimensional materials both in fundamental researches and technological applications. However, the gapless feature shrinks the applications of pristine graphene. Recently, researchers have new challenges and opportunities for post-graphene two-dimensional nanomaterials, such as silicene (Si), germanene (Ge), and tinene (Sn), due to the large enough energy gap (of the size comparable to the thermal energy at room temperature). Apart from the graphene analogs of group IV elements, the buckled honeycomb lattices of the binary compositions of group III-V elements have been proposed as a new class of post-graphene two-dimensional nanomaterials. In this study, the generalized tight-binding model considering the spin-orbital coupling is used to investigate the essential properties of monolayer GaAs. The Landau quantization, band structure, wave function, and density of states are discussed in detail.

title: Magnetic quantization in monolayer GaAs abstract: Since 2004, the discovery of graphene has opened the possibility of two-dimensional materials both in technological applications and fundamental researches. However, the gapless feature limits the applications of pristine graphene. Recently, researchers have new opportunities and challenges for post-graphene two-dimensional nanomaterials, such as silicene (Si), germanene (Ge), and tinene (Sn), owing to the sufficiently large energy gap (of the size comparable to the thermal energy at room temperature). Apart from the group IV elements, the buckled honeycomb lattices of the binary compositions of group III-V elements have been proposed as a new class of post-graphene two-dimensional nanomaterials. In this study, the generalized tight-binding model including the spin-orbital interactions is utilized to investigate the essential properties of monolayer GaAs. The magnetic quantization, band structure, wave function, and density of states are discussed in detail. (One of us (Hsien-Ching Chung) thanks Ming-Hui Chung and Su-Ming Chen for financial support.

Substrate and BMT Inter Layer Effect on Pulsed Laser Deposited Barium Strontium Titanate Thin Films and Its Microwave Properties

Tue, 24 Jun 2014 02:00:36 GMT

title: Substrate and BMT Inter Layer Effect on Pulsed Laser Deposited Barium Strontium Titanate Thin Films and Its Microwave Properties abstract: We have deposited epitaxial Ba0.4Sr0.6TiO3 (BST) thin films via laser ablation on to SiO2 and Pt(Si) substrates with or without a Ba(Mg1/3Ta2/3)O3 (BMT) buffer layer. The structure and microwave dielectric properties of the films have been investigated with two different substrates and a BMT buffer layer. We have found that BMT buffer layer enhances the crystalline growth behavior and also effects dielectric properties of the BST film. The incorporation of BMT buffer layer engenders a change in the lattice parameter BST of the order of 0.01277 on SiO2 substrates and 0.01189 on Pt-Si Substrates. The evanescent microprobe (EMP) analysis reveals the close relation in the variation of microwave property of the deposited films allied with the variation in lattice parameter and the grain size/shape.

title: 以MPECVD法製作三種不同大小尺寸的鑽石薄膜特性研究 abstract: 本實驗利用微波電漿輔助化學氣相沈積法(MPECVD)成長3種不同尺寸(Grain size)的鑽石薄膜，並利用SEM來探討表面顆粒大小的差異，以Raman光譜來探討鑽石薄膜顆粒結晶大小的差異性，以解釋薄膜場發射特性的不同；分別製作約500-600nm、100-200nm和約30nm的鑽石薄膜，發現大小約500-600nm的鑽石薄膜顆粒結晶程度最好，但是以場發射的特性可以發現約30nm大小的鑽石薄膜有較好的電流密度，其次為100-200nm大小的鑽石薄膜，而擁有最好結晶性的500-600nm的鑽石薄膜卻是這三種薄膜裡場發射的電流密度最差的。

title: 通訊用介電薄膜電極奈米碳管與電場加強因子與臨場電漿物種相關性研究 abstract: 本實驗是以微波電漿輔助化學汽相沉積法在鐵針尖合成奈米碳管，再使用光多頻分析儀擷取臨場電漿發射光，並利用以氬氣比甲烷95:5和97.5:2.5的濃度來生長奈米碳管。然後再量測碳管場發射特性決定其電場增強因子beta。結果發現了催化劑鐵物種濃度的含量Fe66%所對應的beta為最大值60，因此可知奈米碳管電場增強因子與電漿鐵物種濃度有極密切相關性。

title: 硼摻雜之奈米鑽石薄膜的場發射特性研究 abstract: 本實驗利用微波引致電漿化學汽相沉積法(MPECVD)在矽(Si)基板上成長UNCD (Ultra-nano crystalline diamond)，陸續依比例參數通入所需摻雜的氣體(如硼(B)、甲烷(CH4)、氬氣(Ar))，在氬氣(Ar)和甲烷(CH4)流量比為99:1的電漿(Plasma)中，逐步將微波功率由500W提昇至750W來持續提供電漿(Plasma)能量，氣體總流量則由80 torr提昇至130 torr且維持於此，此外，本實驗在矽(Si)基板上所成核的形成層，則是使用BEN(Bias enhance nucleation)成核，在氣氛中，則是利用甲烷(CH4)做為沉積鑽石的碳源，以不同的成長參數(氣體比例、摻雜與否、磊晶時間)來控制奈米鑽石薄膜的沉積，針對不同的參數改變(摻雜氣體的氣體比例)，透過原子力顯微鏡(AFM)量測CITS，探討不同鑽石薄膜摻雜硼的成長參數對電子場發射特性的影響。

Fabrication of nitrogen-doped ultrananocrystalline diamond nanowire arrays with enhanced field emission and plasma illumination performance

Tue, 18 Mar 2014 01:51:50 GMT

title: Fabrication of nitrogen-doped ultrananocrystalline diamond nanowire arrays with enhanced field emission and plasma illumination performance abstract: Large-area silicon nanowire arrays (SiNAs) were fabricated via metal catalytic etching technique, in conjunction with the polystyrene spheres lithographic process. The nitrogen-doped ultrananocrystalline diamond (N2-UNCD) films were coated on thus formed SiNA by using microwave plasma chemical vapor deposition (MPECVD) process. The N2-UNCD/SiNWs films, which were grown in CH4/N2 plasma at 700°C, possess markedly better conductivity (σN2-UNCD=2-3(Ω cm)-1) than the conventional c-UNCD/SiNWs films, which were grown in CH4/Ar plasma at around 425°C (σUNCD=0.01(Ω cm)-1). The EFE process of the former materials can be turned on at (E0)N2-UNCD=7.80 V/μm achieving larger EFE current density of (Je)N2-UNCD=0.67 mA/cm2 at an applied field of 13.0 V/μm, whereas that of the latter materials need (E0)=UNCD=18.25 V/μm to turn on, attaining only (Je)UNCD=0.024 mA/cm2 at same applied field. While the plasma illumination process can be triggered at around 0.21 V/μm, regardless of the characteristics of the cathod materials, plasma illumination intensity/current density is larger when the materials with better EFE properties were used as cathodes for the plasma device. The plasma illumination current density is around (Jpi)N2-UNCD=5.0 mA/cm2 (at an applied field of 0.35 V/μm) when N2-UNCD/SiNWs film was used as cathode, whereas the (Jpi)UNCD=3.2 mA/cm2 when the conventional UNCD/SiNWs film was used as cathode. In summary, it is observed that the plasma illumination characteristics of the CP-devices is closely correlated with the electron field emission behavior of the cathode materials, which, in turn, was enhanced - ue to the improvement in conductivity of the UNCD films

The operating mechanism of Schottky-gate nanosensors

Thu, 09 Feb 2012 07:55:38 GMT

title: The operating mechanism of Schottky-gate nanosensors abstract: The highly sensitive nanowire-based Schottky-gate nanosensors for detecting UV, bio-molecules, and gas sensing were demonstrated. The operating mechanism of the Schottky-gate nanosensors is totally distinct from the conventional Ohmic contacted nanosensors. The Schottky-gated device (SGD) has a few merits in comparison to the conventional Ohmic contacted device (OCD). First, it needs no bio-probe to detect molecules; rather, it depends on the absorption of the charged molecules to the junction region. Second, as for the same type of nanowires, such as ZnO, the sensitivity of the SGD is much higher than that of OCD, because a few molecules at the junction region can change the “gate” that effectively tunes the conductance. This Schottky-gate-modulation based sensing principle can be applied to other materials and sensing systems.
