Electrical Characterization

For electrical characterization of conductors, semiconductors, dielectrics and particle-filled polymers, CeSMA can offer the following services:

Characterization of conductive elastomers:

• Conductivity under linear and radial strain
• Endurance testing: conductivity under cyclical linear strain
• 2 point / 4 point measurement using LCR meter

Broadband Dielectric Spectroscopy:

• Determination of capacity, specific conductivity, impedance, permittivity and loss factor
• Parameters: Frequency range 10^-5 to 10⁷ Hz, temperature range -150 °C to approx. 400 °C, voltage up to +/- 500 V)
• Equipment: Novocontrol, Type Alpha-A Analyzer with Quatro Cryosystem, ZGS Alpha Active Sample Cell and High Voltage Test Interface HVB1000

Characterization of semiconductors:

• Determination of precise (low) current and voltage (semiconductor) characteristics
• Parameters: sub-pA level up to 1.05 A DC. / max. voltage 42 V
• Diodes: 2-wire (non-kelvin) or 4-wire (kelvin) connections
• Transistors: 2-wire (non-kelvin) connection, drain-current over drain-/gate-voltage
• Equipment: Keysight Source Measurement Unit B2912 (dual channel) + test fixtures (dark ambient) + triaxial connections
