Contact: Fernando Camino and Chang-Yong Nam The electrical characterization lab hosts these major instruments: - LakeShore Model 8404 Hall Effect Measurement System allows measurement of mobilities down to 0.001 cm2/Vs and resistances from 0.5 mWto 100 GW. Samples can be measured at room temperature and at 77 K. - LakeShore HFTTP4 cryogenic probe station is designed for low-noise, DC to 50 MHz, measurements from 4 K up to 400 K under in-plane magnetic fields up to 1 Tesla. Optical sources can be introduced through a viewport window or a fiber optic probe arm. - Signatone CM-170 probe station is perfect for routine electrical characterization at room temperature. It is reliable and simple to use. - Rucker and Kolls probe station is suited for studying optoelectronic properties at room temperature. It is fitted with a with a Newport-Oriel solar spectrum simulator and optical monochromator. - MMR's Variable Temperature Micro Probe System allows opto-electrical characterization of samples in the temperature range from 70K to 730K under controlled atmosphere (inert, vacuum etc.) and light condition. - MBE-Komponenten AO500 high-temperature probe station for rapid thermal annealing (up to 500 °C) in vacuum (2 mbar) or in a gas mixture atmosphere (Ar, H2 and N2 regulated by mass flow controllers). The system also allows optical access to the sample and in-situ electrical characterization. - Kulicke & Soffa Model 4526 wire wedge bonder.
