Nanotube molecular wires as chemical sensors
Jing Kong,Nathan R. Franklin,Chongwu Zhou,Michael Chapline,Shu Peng,Kyeongjae Cho,Hongjie Dai +6 more
TL;DR: The nanotubes sensors exhibit a fast response and a substantially higher sensitivity than that of existing solid-state sensors at room temperature and the mechanisms of molecular sensing with nanotube molecular wires are investigated.

Toward Large Arrays of Multiplex Functionalized Carbon Nanotube Sensors for Highly Sensitive and Selective Molecular Detection
TL;DR: In this paper, a polyethyleneimine coating is applied to nanotubes for detecting NO2 at less than 1 ppb (parts-per-billion) concentrations while being insensitive to NH3.

Thermal conductivity of isotopically modified graphene
Shanshan Chen,Qingzhi Wu,Columbia Mishra,Junyong Kang,Hengji Zhang,Kyeongjae Cho,Kyeongjae Cho,Weiwei Cai,Weiwei Cai,Alexander A. Balandin,Rodney S. Ruoff +10 more
TL;DR: The experimental data agree well with the molecular dynamics simulations, corrected for the long-wavelength phonon contributions by means of the Klemens model, and are expected to stimulate further studies aimed at a better understanding of thermal phenomena in 2D crystals.
Unusual infrared-absorption mechanism in thermally reduced graphene oxide
Muge Acik,Geunsik Lee,Cecilia Mattevi,Cecilia Mattevi,Manish Chhowalla,Manish Chhowalla,Kyeongjae Cho,Yves J. Chabal +7 more
TL;DR: The observation of a giant-infrared-absorption band in reduced graphene oxide is reported, arising from the coupling of electronic states to the asymmetric stretch mode of a yet-unreported structure, consisting of oxygen atoms aggregated at the edges of defects.
Band alignment of two-dimensional transition metal dichalcogenides: application in tunnel field effect transistors
TL;DR: In this article, the authors proposed two couples composed of monolayer transition metal dichalcogenides (TMDs) with sizable band gaps for tunnel field effect transistors (TFETs) for low power logic devices.
