Observation of bright and dark exciton transitions in monolayer MoSe2 by photocurrent spectroscopy
Jorge Quereda, Talieh S. Ghiasi, Feitze A. van Zwol +2
We investigate the excitonic transitions in single- and few-layer MoSe2 phototransistors by photocurrent spectroscopy. The measured spectral profiles show a well-defined peak at th…
Analysis of optical differential transmission signals from co-propagating fields in a lambda system medium
J. P. de Jong, A. R. Onur, D. Reuter +2
We analyze theoretically and experimentally how nonlinear differential-transmission spectroscopy of a lambda-system medium can provide quantitative understanding of the optical dip…
The annealing mechanism of AuGe/Ni/Au ohmic contacts to a two-dimensional electron gas in GaAs/AlGaAs heterostructures
E. J. Koop, M. J. Iqbal, F. Limbach +6
Ohmic contacts to a two-dimensional electron gas (2DEG) in GaAs/AlGaAs heterostructures are often realized by annealing of AuGe/Ni/Au that is deposited on its surface. We studied h…
