Cambridge Graphene Centre

Research Centre on Graphene, Layered Crystals and Hybrid Nanomaterials
 

Our SEM lab is for examining structures on the nano-scale, and analysing the elemental content using the EDX.

 

For access to the lab, or for any general training, please contact the lab leader, Dr Yang Li, or their deputy Dr Youngjin Ham,  For training on any of the equipment, please contact the Principal User or their deputy for the listed equipment.

All equipment in the SEM Lab needs to be booked before use. The booking system can be found here.

 

SEM – EDX

Model: Magellan 400

 

SEM equipped with a load-lock, an in-lens and a back-scatter secondary electron detectors (normal imaging), Bruker X-ray detector (elemental analysis), stage bias (imaging dielectric samples), two CCDs for sample navigation and stage side view.

 

A mini sputter-coater is available in the SEM lab to pre-coat SEM specimens with a conducting layer (Al, Au and C targets are available).

This tool is to be used ONLY in conjunction with the SEM work.

 

Users in Charge:

Leader: Dr Yang Li

Deputy: Dr Youngjin Ham

 

 

Sputter Coater

Model:

 

 

Quick and easy way to sputter-deposit conducting layers of Al, Au and C onto samples before SEM. This tool is to be used ONLY in conjunction with SEM work.

 

Users in Charge:

Leader: Dr Yang Li

Deputy: Dr Youngjin Ham

 

 

 

Wire Bonder

Model: HB16

 

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

 

Users in Charge:

Leader: Dr Yang Li

Deputy: Dr Jincan Zhang

 

 

 

 

 

 

Solar Simulator

Model: Sol3A Class AAA Solar Simulators

 

A Solar Simulator is a light source that approximates the illumination of natural sunlight. Solar simulators with various tailored spectral output are used to to test a variety of samples including but not limited to solar cells, sun screen (SPF), materials photo-stability, and other samples (in-vivo or in-vitro) under controlled, repeatable, laboratory conditions.

 

Users in Charge:

Leader: Sohail Abbas

Deputy: Matteo Tiberi

 

 

 

 

 

Quantum Efficiency Measurement System

Model: 

The "quantum efficiency" (Q.E.) is the ratio of the number of carriers collected by the solar cell to the number of photons of a given energy incident on the solar cell. This system is designed to acheive the measurement.

 

Users in Charge:

Leader: Matteo Tiberi
