The Electroluminescence Laboratory allows the electro-optical characterization of micro/nano-electronic devices. Two darkened probe stations, resting on optical tables, are available. One is connected to a semiconductor parameter analyzer and a precision LCR meter, which make it possible to perform electrical tasks such as current-voltage, capacitance-voltage, capacitance-frequency and impedance spectroscopy measurements. The other one is equipped with another semiconductor parameter analyzer, two multichannel scalers, an arbitrary function generator, a digital oscilloscope and a grating monochromator coupled with two nitrogen cooled CCD cameras in the visible and infrared spectral range. This probe station is also equipped with two single photon detection modules, one based on a silicon APD for the visible range, the other based on a InGaAs/InP APD for the near infrared range. The measurements being collected with this setup are electroluminescence spectra (both in DC and AC regime), light emission intesity and time-resolved electroluminescence with resolution of 5 ns.
All the instruments can be controlled by dedicated LabVIEW softwares, which allow for semi-automatic measuring sessions.
