In submicron MOSFET devices, maintaining the ratio between the channel length (L) and the channel depth (D) to 3:1 or larger is known to be critical in preventing the deleterious short-channel effects. In this study, n-type ...

In this paper the effect of intercritical heat treatment on the microstructure and mechanical properties was examined both in the 0.15C-6Mn steels and 0.15C-6Mn steels added with Nb or Ti. This result will be applied into ...

용해/분쇄법으로 제조한 n형 Bi2(Te0.9Se0.1)3 분말에 0.5 vol% TiO2 나노분말을 분산시켜 가압소결 후, TiO2나노분말의 분산이 Bi2(Te0.9Se0.1)3 가압소결체의 열전특성에 미치는 영향을 분석하였다. Bi2(Te0.9Se0.1)3 가압소결체는2.93×10-3 /K의 최대 성능지수 및 1.02의 최대 무차원 성능지수의 우수한 열전특성을 나타내었다. 0.5 vol% ...

Orthorhombic Ba(Ti0.94Zr0.06)O3 single crystals are fabricated using the cost-effective solid-state single crystal growth (SSCG)method; their dielectric and piezoelectric properties are also characterized. Measurements ...

The structure and dielectric properties of poled <001>-oriented 0.7Pb(Mg_(1/3)Nb_(2/3))O_3-0.3PbTiO_3 (PMN-0.3PT) crystals have been investigated for orientations both parallel and perpendicular to the [001] poling direction. ...

Porous carbon has found commercial applications as a filter material based on the sorption ability of its pores. The pore size and surface properties of the carbon can be varied depending on the type of particles to be ...

Copper nano particles have been considered as the materials for conductive ink due to its good thermal, electrical conductivity and low cost. However, copper nanoparticles oxidize easily, decreasing dispersion stability ...

ReMnO3(Re:Y, Ho, Er) thin films were prepared by MOCVD method available to non-volatile memory device with MFS-FET structure. ReMnO3 thin films were deposited on the Si(100) substrate at 700℃ for 2h. When the films were ...

(1 . x)CaWO4 . xYNbO4계에 대하여 YNbO4(0.05 ≤ x ≤ 0.4)의 치환량 변화에 따른 마이크로파 유전특성을 고찰하 였다. x = 0.10 조성까지 정방정(tetragonal) scheelite 구조의 CaWO4 단일상이 확인되었고, 그 이상 첨가 시 fergusonite 구조 의 2차상이 증가하였다. YNbO4 첨가량이 증가할수록 겉보기 밀도는 감소하였는데, 이는 ...
