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 Wing Chung Liu, 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.

Solar SimulatorModel: 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: Dr Wenshuo Xu

Quantum Efficiency Measurement SystemModel: 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.
