Rotary Kelvin Probe System RKP-1
Achieve high-precision, real-time measurement of work function and surface potential!
Main Applications
Work function (Fermi level) measurement on clean metal and semiconductor surfaces
Real-time measurement of surface potential during organic semiconductor film deposition
Features
● High-resolution measurement using a high-precision rotating electrode
● Vacuum compatible: Enables stable measurement unaffected by atmospheric conditions
● Achieves real-time work function and surface potential measurement during film deposition, difficult with vibrating electrodes
● Capable of evaluating band bending at heterointerfaces and orientation polarization in polar molecularly deposited films
● User-friendly measurement software
Supports data acquisition for temperature, pressure, etc.
