On the other hand, stable doping methods are required to adjust its physical properties so MoS 2 can be utilized in practical applications, such as transistors and photodetectors. Molybdenum disulfide (MoS 2) has great potential for next-generation electronic devices. 3Electronic Devices Research Team, Hyundai Motor Group, Uiwang, Gyeonggi, Republic of Korea.2Department of Chemical and Biological Engineering, Gachon University, Seongnam, Gyeonggi, Republic of Korea.1Department of Electronic Engineering, Gachon University, Seongnam, Gyeonggi, Republic of Korea.Dong Hyun Lee 1 Taehyun Park 2 Taeho Jeong 3 Youngkyun Jung 3 Junghee Park 3 Nackyong Joo 3 Uiyeon Won 3 Hocheon Yoo 1*
