Electrical characterization of chemical and dielectric passivation of InAs nanowires
Gregory W. Holloway, Chris M. Haapamaki, Paul Kuyanov +2
The native oxide at the surface of III-V nanowires, such as InAs, can be a major source of charge noise and scattering in nanowire-based electronics, particularly for quantum devic…
Josephson Interference due to Orbital States in a Nanowire Proximity Effect Junction
Kaveh Gharavi, Gregory W. Holloway, Chris M. Haapamaki +4
The Josephson supercurrent in a Nb-InAs nanowire-Nb junction was studied experimentally. The nanowire goes superconducting due to the proximity effect, and can sustain a phase cohe…
Sensitive Magnetic Force Detection with a Carbon Nanotube Resonator
Kyle Willick, Chris Haapamaki, Jonathan Baugh
We propose a technique for sensitive magnetic point force detection using a suspended carbon nanotube (CNT) mechanical resonator combined with a magnetic field gradient generated b…
Magnetoconductance signatures of subband structure in semiconductor nanowires
Gregory W. Holloway, Daryoush Shiri, Chris M. Haapamaki +4
The radial confining potential in a semiconductor nanowire plays a key role in determining its quantum transport properties. Previous reports have shown that an axial magnetic fiel…
Trapped charge dynamics in InAs nanowires
Gregory W. Holloway, Yipu Song, Chris M. Haapamaki +2
We study random telegraph noise in the conductance of InAs nanowire field-effect transistors due to single electron trapping in defects. The electron capture and emission times are…
Temperature-dependent electron mobility in InAs nanowires
Nupur Gupta, Yipu Song, Gregory W. Holloway +4
Effective electron mobilities are obtained by transport measurements on InAs nanowire field-effect transistors at temperatures ranging from 10-200 K. The mobility increases with te…
