Real-time detection of every Auger recombination in a self-assembled quantum dot
Pia Lochner, Annika Kurzmann, Jens Kerski +6
Auger recombination is a non-radiative process, where the recombination energy of an electron-hole pair is transferred to a third charge carrier. It is a common effect in colloidal…

Patterning of diamond with 10 nm resolution by electron-beam-induced etching
Vasilis Dergianlis, Martin Geller, Dennis Oing +2
We report on mask-less, high resolution etching of diamond surfaces, featuring sizes down to 10 nm. We use a scanning electron microscope (SEM) together with water vapor, which was…

Giant magneto-photoelectric effect in suspended graphene
Jens Sonntag, Annika Kurzmann, Martin Geller +3
We study the optical response of a suspended graphene field-effect transistor in magnetic fields of up to 9 T (quantum Hall regime). With an illumination power of only 3 μW, we mea…
