Anomalous CDW ground state in Cu2Se: A wave-like fluctuation of the dc I-V curve near 50 K
Mengliang Yao,Weishu Liu,Xiang Chen,Xiang Chen,Zhensong Ren,Stephen D. Wilson,Zhifeng Ren,Cyril Opeil +7 more
TL;DR: In this paper, a charge density wave (CDW) ground state is observed in polycrystalline Cu2Se below 125 k, which corresponds to an energy gap of 40.9 −meV and an electron-phonon coupling constant of 0.6.
Journal ArticleDOI

Keith Gregorczyk,Brian R. Kimball,Joel B. Carlson,Asher Pembroke,Krzysztof Kempa,Zhifeng Ren,Chandra S. Yelleswarapu,Thomas J. Kempa,G. Benham,Y. Wang,Wei Li,Andrzej Herczynski,Jacob Rybczynski,D. V. G. L. N. Rao +13 more
TL;DR: The optical properties of periodic and nonperiodic arrays of aligned multiwalled carbon nanotubes are presented in this paper, where experimental analysis indicates a complex optical response that is attributed to both the individual carbon-nanotube scatterers and also to the array ensembles.
Journal ArticleDOI
The Promise of Nanocomposite Thermoelectric Materials
Mildred S. Dresselhaus,Gang Chen,Zhifeng Ren,Kenneth McEnaney,G. Dresselhaus,Jean-Pierre Fleurial +5 more
TL;DR: The concept of using nanocomposite thermoelectric materials in bulk form for practical applications is presented in this article, where specific examples are presented of nano-structured materials developed by the group based on the familiar silicon germanium system.
Biosensors Based on Carbon Nanotubes
TL;DR: In this paper, the authors summarized the recent development of carbon nanotube based electrochemical biosensors work at PNNL and proposed a new method based on the nanotubes.
