Polarization sensitive solar-blind detector based on a-plane AlGaN
Masihhur R. Laskar, A. Arora, A. P. Shah +3
We report polarization-sensitive solar-blind metal-semiconductor-metal UV photodetectors based on (11-20) a-plane AlGaN. The epilayer shows anisotropic optical properties confirmed…
Tunable thermal conductivity in defect engineered nanowires at low temperatures
Sajal Dhara, Hari S. Solanki, Arvind Pawan R. +7
We measure the thermal conductivity () of individual InAs nanowires (NWs), and find that it is 3 orders of magnitude smaller than the bulk value in the temperature range of 10 t…
Facile fabrication of lateral nanowire wrap-gate devices with improved performance
Sajal Dhara, Shamashis Sengupta, Hari S. Solanki +5
We present a simple fabrication technique for lateral nanowire wrap-gate devices with high capacitive coupling and field-effect mobility. Our process uses e-beam lithography with a…
Distorted wurtzite unit cells: Determination of lattice parameters of non-polar a-plane AlGaN and estimation of solid phase Al content
Masihhur R. Laskar, Tapas Ganguli, A. A. Rahman +3
Unlike c-plane nitrides, ``non-polar" nitrides grown in e.g. the a-plane or m-plane orientation encounter anisotropic in-plane strain due to the anisotropy in the lattice and therm…
Anisotropic structural and optical properties of a-plane (11-20) AlInN nearly-lattice-matched to GaN
Masihhur R. Laskar, Abdul Kadir, A. A. Rahman +4
We report epitaxial growth of a-plane (11-20) AlInN layers nearly-lattice-matched to GaN. Unlike for c-plane oriented epilayers, a-plane Al_{1-x}In_{x}N cannot be simultaneously la…
Magnetotransport properties of individual InAs nanowires
Sajal Dhara, Hari S. Solanki, Vibhor Singh +5
We probe the magnetotransport properties of individual InAs nanowires in a field effect transistor geometry. In the low magnetic field regime we observe magnetoresistance that is w…
