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 [...]

Kong K-J, Chang H., Lee J-O, Korea Research Institute of Chemical Technology, KR

Here, we have briefly introduced the recent progresses in experiments of DNA sensing with CNT-FET sensors and theoretical investigations to explore the sensing mechanism.

First-Principles Studies of SnS2 Nanotubes

Chang H., In E., Kong K-J, Lee J-O, Choi Y., Ryu B-H, Korea Research Institute of Chemical Technology, KR

First principles calculations are used to predict the stability and electronic structures of SnS2 nanotubes. Optimization of several structures and their corresponding strain energies confirms the stability of SnS2 nanotube structures. Band structure calculations show [...]
