A selection of the research facilities available in our group:

Cleanroom

A cleanroom class 7 with several glove boxes for spin coating, evaporators and preparation of solutions

Evaporator inside glovebox

Evaporators for deposition of thin layers of metals/compounds or organic materials

Spincoater inside glovebox

Spin coaters outside (air environment) or inside glove box (N2 environment)

Dektak profilometer

Bruker Dektak XT profilometer to determine layer thickness and (large scale) roughness. Computer controlled XY table, vertical resolution down to nanometer scale, horizontal range μm – cm

PL laser setup

Photoluminescence (PL) set-up: Titanium sapphire laser (Mira900) based femtosecond laser excitation. Steady state and time resolved (up to 1 ps resolution) measurements in the visible and NIR spectral range thanks to sets of Hamamatsu streak cameras and steady state detectors. The set-up is equipped with a second and third harmonic generator and it can be coupled to the confocal microscope.

Nikon Eclipse Ti

Nikon Eclipse Ti confocal inverted microscope

Pump probe set-up

Self-built transient absorption set-up based on a supercontinuum laser source and an auto-balanced photodetector. The laser covers a spectral range from 400 to 1400 nm with an overall time resolution of around 10 ps. A maximum delay of 6 ns is possible in the current configuration. Also see our publication .
