Electrical measurements laboratory

Electrical measurements laboratory including: a tpt HB05 wire bonding machine, 2 LAKE SHORE cryo-probers for electrical measurements in the temperature range of 10 K – 400 K; one with vertical magnetic field up to 2.5 T, and one with horizontal magnetic field up to 1.5 T, each with at least 3 micro-manipulated arms with contact needles allowing electrical measurements under various electric/magnetic fields and illumination conditions; 4 cryostats, covering a temperature range between 10 K and 800 K; 2 DLTS (Deep-Level Transient Spectroscopy), 2 TSC (Thermally Stimulated Current/Capacitance) systems,  for the investigation of electrically active defects (trapping parameters and defect concentrations) in materials and MOS-like structures; Van der Pauw and Hall measurement systems in the 80K-800 K temperature range; KP020 Kelvin-Probe System for measuring work function/surface potential, set-up for pyroelectric measurements; ferritesters; various instruments for measuring currents, resistances and voltages (electrometers, nanovoltmeters, Lock-In amplifiers); voltage and current sources; RLC bridges and impedance analysers. These facilities are used to perform complex characterization of electrical (hysteresis loops; C-V and I-V characteristics; impedance spectroscopy; defect spectroscopies; etc.) and superconductive properties (electron transport, thermodynamics, magnetic-field penetration depth measurements); determination of the d33 piezoelectric coefficient.
