Impedance Spectroscopy (EIS)

For analyzing complex electrical behavior over a wide frequency range (1 mHz to 1 MHz), suitable for:

 

Solid-state ionic conductors

 

Supercapacitors and batteries

 

Fuel cells and electrochemical sensors

We extract Nyquist, Bode, and Cole–Cole plots for modeling equivalent circuits (R-C, R-L, Warburg, etc.).

Equipment and Setup Options:

Four-point probe station (manual/automated)

 

Source Measure Units (SMUs) for I–V/C–V testing

 

Hall effect system with magnetic field up to 1 Tesla

 

LCR meters (precision, high-frequency range)

 

Impedance analyzer with customized test cells

 

Probe stations with light sources (LED, laser, solar simulators)

 

Temperature-controlled stages (room temperature to 200 °C or higher on request)

 

Applications:

Semiconductor device analysis

 

Sensor material optimization

 

Energy storage and conversion devices (batteries, supercapacitors, fuel cells)

 

Functional oxide and ferroelectric studies

 

Thin film and coating quality control

 

Reliability and failure analysis in electronic materials
