(Bi 1/2 Na 1/2 ) 1−x Ca x TiO₃ 세라믹스의 압전 특성 및 상전이 거동
TL;DR: In this paper, the morphotropic phase boundary (MPB) zone which BNT is transformed from rhombohedral to cubic structure was appeared by adding CaTiO₃ with 0.12 ㏖l by the measurement of permittivity and X-ray diffraction.
Photoresponse of Physically Oxidized Graphene Sensitized by an Organic Dye
Jaehun Han,Youngbin Lee,Samudrala Appalakondaiah,Jinshu Li,Xing Gao,Youngjae Yoo,Dongmok Whang,Euyheon Hwang,Jeong Ho Cho +8 more
TL;DR: In this paper, the authors investigated the charge transport and photoresponse characteristics of a hybrid structure comprising physically oxidized graphene and Rhodamine-based organic dye molecules, and found that the photoresponses of the hybrid films were strongly related to chemical reactions between the photoexcited electrons and adsorbates (water or oxygen) in the dye layer.

Graphene barristors for de novo optoelectronics.
TL;DR: Graphene-based vertical Schottky-barrier transistors (SBTs), renowned as graphene barristors, have emerged as a feasible candidate to fundamentally expand the horizon of conventional transistor technology as mentioned in this paper .
