AdverSAR: Adversarial Search and Rescue via Multi-Agent Reinforcement Learning
Aowabin Rahman, Arnab Bhattacharya, Thiagarajan Ramachandran +4
Search and Rescue (SAR) missions in remote environments often employ autonomous multi-robot systems that learn, plan, and execute a combination of local single-robot control action…
Layered transition metal dichalcogenides: promising near-lattice-matched substrates for GaN growth
Priti Gupta, A. A. Rahman, Shruti Subramanian +10
Most III-nitride semiconductors are grown on non-lattice-matched substrates like sapphire or silicon due to the extreme difficulty of obtaining a native GaN substrate. We show that…
Comparison of GaN nanowires grown on c-, r- and m-plane sapphire substrates
Carina B. Maliakkal, A. Azizur Rahman, Nirupam Hatui +3
Gallium nitride nanowires were grown on c-plane, r-plane and m-plane sapphire substrates in a showerhead metalorganic chemical vapor deposition system using nickel catalyst with tr…
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…
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…
