My research focusses on the characterisation of the opto-electronic properties of quantum dot solids, formed by the self-assembly of nanocrystals.

The aim is to gain novel insights into the relationship between electronic and structural properties of these versatile materials to create new nanomaterial-based opto-electronic devices, as transistors, photodetectors, solar cells, LEDs, etc.

The experimental efforts combine nanocrystal self-assembly with microfabrication, soft-lithography and the characterisation of electronic and structural properties via transistor measurements, SEM imaging, X-ray scattering, etc.

In our current study, I investigate the ultrafast photoresponse time of nanomaterial-based optoelectronic switches or photodetectors, which can be determined using the two-pulse coincidence technique in combination with asynchronous optical sampling.
