Ab-initio prediction of temperature-dependent dielectric constants and curie temperatures of cubic phase perovskite materials

Autor: Won-Joon Son, Mun-Bo Shim, Woon Ih Choi, Inkook Jang, Doh Won Jung, Dae Sin Kim, Dae Jin Yang

Publikováno v: MRS Communications. 11:436-442

Lattice anharmonicity is the essential ingredient for the description of the temperature-dependent dielectric response. Herein, using self-consistent phonon theory calculations that consider the lattice anharmonicity, we examined computational workfl

Enhanced Thermoelectric Performance of p-Type Bi-Sb-Te Alloys by Codoping with Ga and Ag

Autor: Jeong Hoon Lee, Hee Jung Park, Soon-Mok Choi, Sungwoo Hwang, Weon Ho Shin, Kyu Hyoung Lee, Sang-Il Kim, Jong Wook Roh, Sung Wng Kim, Dae Jin Yang

Publikováno v: Journal of Electronic Materials. 44:1531-1535

We report an enhancement of the thermoelectric performance in spark-plasma-sintered polycrystalline p-type Bi0.42Sb1.58Te3 by codoping with Ga and Ag at Bi/Sb-site. Through controlled doping of Ga (n-type) and Ag (p-type), electronic transport proper

Highly sensitive and selective hydrogen sulfide and toluene sensors using Pd functionalized WO3 nanofibers for potential diagnosis of halitosis and lung cancer

Autor: Jong-Jin Park, Namhoon Kim, Jihyun Bae, Il-Doo Kim, Dae-Jin Yang, Seon-Jin Choi

Publikováno v: Sensors and Actuators B: Chemical. 193:574-581

In this work, we report a remarkably improved toluene response and superior cross-sensitivity against H 2 S molecules by combining Pd catalysts and highly porous WO 3 nanofibers (NFs). We functionalized Pd catalysts inside and/or outside of WO 3 NFs

Nanoscale Chemical and Electrical Stabilities of Graphene-covered Silver Nanowire Networks for Transparent Conducting Electrodes

Autor: Sung Heo, Woon Ih Choi, Dong-Jin Yun, Seong Heon Kim, Kwang Hee Kim, Dae Jin Yang

Publikováno v: Scientific Reports

The hybrid structure of Ag nanowires (AgNWs) covered with graphene (Gr) shows synergetic effects on the performance of transparent conducting electrodes (TCEs). However, these effects have been mainly observed via large-scale characterization, and pr
