Integrated phase-Change memory in Bi2Te3 nanowires

Han N.A., Kim S.I., Yang J.D., Lee K., Sohn H., So H-M, Sohn H., Ahn C.W., Yoo K.H., Yonsei University, KR

Bismuth telluride (Bi2Te3) and its alloys are considered to be the best avaiable materials for near room-temperature thermoelectric applications. Moreover, because low-dimensional thermoelectric materials are expected to have a higher figure of merit due to [...]

First-principles studies of electrophilic molecules on the carbon nanotubes

Park S., Kong K-J, So H-M, Buh G-H, Lee J-O, Chang H., Korea Research Institute of Chemical Technology, KR

Recently we have reported that some electrophilic molecules, such as 2,4,6-triphenylpyrylium tetrafluoroborate (2,4,6-TPPT) and 1,3-benzodithiolylium tetrafluoroborate (1,3-BDYT), preferentially interact with metallic single-walled carbon nanotubes (SWNTs). It resulted in selective suppression of conductance in metallic carbon [...]
