Surface hydrogeneration of vanadium dioxide nanobeam to manipulate insulator-to-metal transition using hydrogen plasma
Autor: Hyunwoo Kang, Minhwan Ko, Hyobin Choi, Wanggon Lee, Ranveer Singh, Mohit Kumar, Hyungtak Seo
Publikováno v: Journal of Asian Ceramic Societies, Vol 9, Iss 3, Pp 1310-1319 (2021)
This report suggests the process of hydrogen doping in vanadium dioxide (VO2) nanobeam using hydrogen plasma, and in turn reveals the modification in the structural, chemical, physical, and electrical properties of VO2 nanobeam that are associated wi

Thermoelectric properties of Nb-doped SrTiO3 films prepared by co-sputtering
Autor: Jinseo Kim, Le Thai Duy, Sang Yeon Lee, Minhwan Ko, Hyungtak Seo
Publikováno v: Journal of Asian Ceramic Societies, Vol 8, Iss 4, Pp 1135-1146 (2020)
SrTiO3 (STO), a member of perovskite structure materials, exhibits a large thermoelectric figure of merit at high temperatures. Theoretically, its property can be significantly improved by niobium (Nb) dopant. So far, the synthesis method of Nb-doped

Significant control of metal-insulator transition temperature through catalytic excessive oxygen doping in high-performance vanadium dioxide nanobeam channel
Autor: Sang Yeon Lee, Hyungtak Seo, Minhwan Ko, Jucheol Park
Publikováno v: Journal of Materials Science & Technology. 44:96-101
The strategy of a reliable transition temperature control of vanadium dioxide (VO2) is reported. Rectangular VO2 nanobeams were synthesized by a thermal chemical vapor deposition (TCVD) system. The metal-insulator transition (MIT) temperature increas
