FOCUS OF RESEARCH
The aim was to create a platform with to tools to carry out user configurable experiements to investage optical and optoelectronic properties of materials and devices.
The platform at the moment concentrates on CW measurements of Photoluminescence of materials at room and low temperature. In addition, photocurrent measurements can be carried out as a function of excitation wavelengths at room and cryogenic temperatures.The platform is easily upgradable to incorporate time dependent optical measurements in the future.
