Electronics

Our Electronics lab is for electrical analysis of graphene products.

 

For access to the lab, or for any general training, please contact the Principal Users or their Deputies, listed below. 

While there is a range of devices in the Electronics lab, several of them require booking before use. The booking system can be found here.

 

Physical Property Measurement System (PPMS) - DynoCool from Quantum Design


Principal User: Dr Yang Li
Deputy: Dr Kunjalata Majhi

A closed cycle refrigerator based testing system, which operates from 1.8 K to 400 K. The system allows applying +/- 14 Tesla at all temperatures of operation. Electrical Transport and DC Resistivity measurements can be performed. Cooling down to 1.8K from room temperature can be achieved in 1h.

PPMS

Lakeshore probe station


Principal User: Dr Yang Li
Deputy: Abdulaziz Almutairi

A cryogen-free, closed-cycle refrigerator probe station enhanced with a vertical field superconducting magnet of ±2.5 T and temperature control of 10 K to 500 K. C-V, I-V, microwave, electro-optical probing and out-of-plane vertical magnetic field measurements are executable.


Cascade probe station


Principal User: Patrik Gubeljak
Deputy: Hamideh Ramezani

A Cascade Summit series semi-automated probe system with loading wafer size large up to 200 mm in diameter. High-precision device characterizations and on-wafer RF/Microwave measurements (up to 1.1THz) with wafer level reliability and yield enhancement are accessible on this probe station.


EverBeing Probe Station


Principal User: Patrik Gubeljak
Deputy: Hamideh Ramezani

4-inch coaxial chuck stage based electrical probe station integrated with 4 high-precision SMUs, making this facility available to many electrical measurements, such as I-V, impedance, sheet resistance, contact resistance over various materials at room temperature.


Scanning Microwave Microscope (SMM)


Principal User: Patrik Gubeljak
Deputy: Hamideh Ramezani

A system which integrates electrical measurement capabilities of a vector network analyzer with spatial resolution of an atomic force microscope, is capable of mapping many properties of materials, such as impedance, capacitance, dielectric constant and dopant concentration etc.


Wire bonder


Principal User: Dr Kunjalata Majhi
Deputy: Dr Yang Li

Wedge, ball and ribbon bonding making use of Gold, Aluminium, Silver and Copper wires can be performed as using this facility either in manual or automatic mode.
