Higgs mass and vacuum stability in the Standard Model at NNLO [PDF]

, 2012
A bstractWe present the first complete next-to-next-to-leading order analysis of the Standard Model Higgs potential. We computed the two-loop QCD and Yukawa corrections to the relation between the Higgs quartic coupling (λ) and the Higgs mass (Mh ...

Cosmological and Astrophysical Probes of Vacuum Energy [PDF]

, 2015
Vacuum energy changes during cosmological phase transitions and becomes relatively important at epochs just before phase transitions. For a viable cosmology the vacuum energy just after a phase transition must be set by the critical temperature of the ...

Research on the Withstand Voltage Properties of Cr/Mn-Doped Al₂O₃ Ceramics in Vacuum

Electronic Materials
Al2O3 ceramics are widely used in vacuum electronic devices. However, surface flashover in a vacuum during the application of high voltage significantly influences their reliability and restricts the development of vacuum electronic devices.

Improved Contacts to MoS2 Transistors by Ultra-High Vacuum Metal Deposition. [PDF]

Nano letters (Print), 2016
The scaling of transistors to sub-10 nm dimensions is strongly limited by their contact resistance (RC). Here we present a systematic study of scaling MoS2 devices and contacts with varying electrode metals and controlled deposition conditions, over a ...
