Herstellung und Charakterisierung von Einzelphotonendetektoren

What it is about

In this internship you fabricate single-photon detectors using micro- and nanofabrication and characterize them electrically and optically. You will learn all steps from the fabrication of superconducting films to the measurement of the detection efficiency of individual photons and will be able to evaluate the device performance in the end.

What you will be able to do

evaluate the theoretical foundations of single-photon detectors and their applications in quantum technologies
fabricate superconducting films using sputtering
apply micro- and nanofabrication (electron beam lithography, optical lithography, RIE etching, electron-beam metallization, ...)
characterize electrical and optical quantum technology building blocks
assess the metric of single-photon detectors

What the module consists of

PraktikumFabrication and characterization of single-photon detectors; practical work in the laboratory
