Microwave response of a metallic superconductor subject to a high-voltage gate electrode
Giacomo Catto, Wei Liu, Suman Kundu +3
Processes that lead to the critical-current suppression and change of impedance of a superconductor under the application of an external voltage is an active area of research, espe…
Imaging non-radiative point defects buried in quantum wells using cathodoluminescence
Thomas Weatherley, Wei Liu, Vitaly Osokin +5
Crystallographic point defects (PDs) can dramatically decrease the efficiency of optoelectronic semiconductor devices, many of which are based on quantum well (QW) heterostructures…
Direct evidence of electron-hole compensation for XMR in topologically trivial YBi
Shaozhu Xiao, Yinxiang Li, Yong Li +9
The prediction of topological states in rare earth monopnictide compounds has attracted renewed interest. Extreme magnetoresistance (XMR) has also been observed in several nonmagne…
Electronic structure and - phase diagram of Eu(FeRh)As
Shaozhu Xiao, Darren C. Peets, Wei Liu +9
The iron-based superconductors represent a promising platform for high-temperature superconductivity, but the interactions underpinning their pairing present a puzzle. The EuFe…
A broadband microwave Corbino spectrometer at He temperatures and high magnetic fields
Wei Liu, LiDong Pan, N. P. Armitage
We present the technical details of a broadband microwave spectrometer for measuring the complex conductance of thin films covering the range from 50 MHz up to 16 GHz in the temper…
Microwave Spectroscopy Evidence of Superconducting Pairing in the Magnetic-Field-Induced Metallic State of InO Films at Zero Temperature
Wei Liu, LiDong Pan, Jiajia Wen +3
We investigate the field tuned quantum phase transition in a 2D low-disorder amorphous InO film in the frequency range of 0.05 to 16 GHz employing microwave spectroscopy. In th…
Broadband microwave and time-domain terahertz spectroscopy of CVD grown graphene
W. Liu, R. Valdés Aguilar, Y. Hao +2
We report a study of the complex AC impedance of CVD grown graphene. We measure the explicit frequency dependence of the complex impedance and conductance over the microwave and te…
