Electrical Measurements

The electrical characterizations can be done using :

• Keithley 6517A Electrometer for measuring high resistance and small current measurements (100 aA resolution in 20 pA range).
• Keithley 4200-SCS Parameter Analyzer with 4 SMU (source measure unit), 1 PMU (ultra-fast pulse measure unit), 1 CVU (capacitance voltage unit: 1kHz-10MHz ) and Remote Preamplifier/Switch module.

• Keithley 6221 DC and AC current source (AC currents from 4 pA to 210 mA with sine waves up to 100 kHz).
• Keithley 236/237 Source Measure Units.
• Stanford Research Systems SR830 Lock-In Amplifiers.
• Stanford Research Systems SR560 low noise Pre-Amplifier.
• HP/Agilent 3458A, 3457A, 3478A DMM.
• Agilent E4980A LCR (20Hz to 2MHz)
• Agilent 4155B Semiconductor Parameter Analyzer
• Cypher ES - Atomic Force Microscope
