Computational facilities in the department include a Silicon Graphics multiprocessor array, high performance workstation clusters, and personal computer clusters. In addition, the Science and Engineering Node Services Group provides Unix servers and the university is home to the Center for Computational Research. We are connected by high-speed Internet and wireless access points. The computing facilities support teaching and research in communications and signals, multimedia communications, multiuser communications, radar and medical image processing, interface design and real-time control, data acquisition and adaptive filtering and simulations of physical devices, systems and networks. VLSI design is performed on workstations using the Cadence design suite. There is also equipment for study in modern control systems, switching logic, sensors and electronic instrumentation.
Facilities for semiconductor and thin-film fabrication include electron cyclotron resonance, plasma-assisted deposition, sputtering and thermal evaporation, laser-assisted deposition and rapid thermal annealing systems. Facilities for device fabrication include clean rooms, mask aligners, a surface profiler, a wire bonding machine, a plasma etching station and an e-beam direct writing machine. Characterization facilities include AFM, SEM, TEM, DLTS, ellipsometer and X-ray diffractometers. Facilities for device characterization include a semiconductor parameter analyzer, a microprobe station, capacitance-voltage and current-voltage measurement setups, including DCIV and low-temperature Hall Effect equipment.
High-power facilities are available for use in high-voltage DC interruption experiments, and power device research and development activities. Modern facilities for fabricating carbon nanotubes, catalysis and energy storage and for processing and characterization of high Tc superconductors are also available in the department. Laser facilities include UV lasers, picosecond and femtosecond lasers, tunable lasers, a streak camera, holographic exposure system, Moire Interference setup and confocal microscopy. The microwave laboratory is equipped with synthesized sweeper, spectrum analyzer and HP8510 network analyzers.
New facilities are being added for the fabrication and characterization of nanostructures to study electronic transport and single-electron detectors for photon counting and quantum cryptography.
Small is about the Nano and Micro for Big Things. Small technology, hybrid nano & microtechnology, is widely used as the tool to answer various science and engineering questions from biotech to defense, telecom to transportation.
SMALL is the nanobioSensors & MicroActuators Learning Lab at University at Buffalo, the State University of New York (SUNY-Buffalo). The lab director is Professor Kwang W. Oh in the Department of Electrical Engineering.
