Engineering of absorbing bulk and sheet composite materials, including nanocomposites, for various EMI applications, requires adequate prediction of frequency and concentration behavior of these composites. This paper proposes two simple analytical formulations for effective permittivity and permeability of magneto-di…
본 연구에서는 염료 태양전지의 제작 시 고가의 TCO전극 대신 간단히 광전극을 대체할수 있는 방법으로 메쉬전극을 이용하는 TCO-less 염료 태양전지를 제작하였다. 이 염료태양전지의 구조는 메쉬전극을 이용하여 “Glass / 메쉬전극(TiO₂를 딥코팅 후 염료를 흡착)/전해질/멤브레인 필터/상대전극(Pt-coated TCO)/Glass로 구성된다. 제작된 샘플의 광전변환 효율은 약 1.5% 였으며, fill factor는 0.55로 나타났다. 향후 효율 향상시킬 수 있는 방법을 도입하여 광전류 밀도와 fill factor를 개선하는 방향으로 연구를 진행할 예정이다.

Les acides biliaires sont des composés naturels existants dans le corps humain. Leur biocompatibilité, leur caractère amphiphile et la rigidité de leur noyau stéroïdien, ainsi que l’excellent contrôle de leurs modifications chimiques, en font de remarquables candidats pour la préparation de matériaux biodégradables po…

In this paper, the CoSi₂ thin films with thicknesses of about 5 ㎛ were deposited on n-type silicon (111) substrates by RF magnetron sputtering method using a CoSi₂ target (99.99%). The flow rate of argon of 50 sccm, substrate temperature of 100 ℃, RF power of 60 watts, deposition time of 30 minutes, and the vacuum of…

We have studied the luminescence of various classes of Er 3+ -doped inorganic phosphors under IR excitation. The highest IR Stokes luminescence efficiency in the range 1.5–1.6 μm is offered by Yb 0.99 Er 0.01 PO 4 (xenotime structure). This efficient IR phosphor has been commercialized under the name AM-1500M-1. It is…

In this paper we investigate the scattering and propagation characteristics of a Gaussian beam impinging upon a dielectric slab with holes, referred to herein as a “holey plate”, which is designed to have a Double negative (DNG) behavior. Our simulation results indicate that the direction of propagation of the Gaussia…

We synthesized ZnO nanowires on Al doped ZnO (AZO) thin film by hydrothermal method. The AZO thin films was deposited on a glass substrate. Then long and vertical ZnO nanowires were synthesized at various mixture solution with fixed quantity of Zinc nitrate, hexamethylenetetramine(HMT), Polyethylenimine(PEI) and a var…

Low-frequency noise (1/f noise) has been measured in order to analyze the Vth instability of ZnO TFTs having two different active layer thicknesses of 40 nm and 80 nm. Under electrical stress, it was found that the TFTs with the active layer thickness of 80 nm shows smaller threshold voltage shift ( ${\Delta}V_{th}$ )…
