Direct Probing of 1/f Noise Origin with Graphene Multilayers: Surface vs. Volume
Guanxiong Liu, Sergey Rumyantsev, Michael S. Shur +1
Low-frequency noise with the spectral density S(f)~1/f^g (f is the frequency and g~1) is a ubiquitous phenomenon, which hampers operation of many devices and circuits. A long-stand…
Selective Gas Sensing with a Single Pristine Graphene Transistor
Sergey Rumyantsev, Guanxiong Liu, Michael S. Shur +2
We show that vapors of different chemicals produce distinguishably different effects on the low-frequency noise spectra of graphene. It was found in a systematic study that some ga…
Graphene-Graphite Quilts for Thermal Management of High-Power GaN Transistors
Zhong Yan, Guanxiong Liu, Javed M. Khan +1
Self-heating is a severe problem for high-power GaN electronic and optoelectronic devices. Various thermal management solutions, e.g. flip-chip bonding or composite substrates have…
Graphene-on-Diamond Devices with Enhanced Current-Carrying Capacity: Carbon sp2-on-sp3 Technology
Jie Yu, Guanxiong Liu, Anirudha V. Sumant +2
Graphene demonstrated potential for practical applications owing to its excellent electronic and thermal properties. Typical graphene field-effect transistors and interconnects bui…
