We directly monitor exciton propagation in freestanding and SiO 2-supported WS 2
monolayers through spatially and time-resolved microphotoluminescence under ambient …

We observe coherent long-distance propagation of an optical pulse in resonance with the
free exciton at high light intensities in an optically thick semiconductor. The experiments …

Highly regular spatiotemporal or multidimensional patterns in the quantum mechanical
probability or classical field intensity distributions can appear due to pair interference …

Excitons in semiconductors can form a variety of collective states leading to different regimes
of exciton propagation. Here we theoretically demonstrate the possibility to reach the …

Linear exciton-polariton propagation in semiconductors is analyzed using a microscopic
theory. Numerical results are compared with various approximation schemes based on …

Pump–probe measurements with a subwavelength spatial resolution of 355 nm and a
temporal resolution of 130 fs have been performed in a multiple quantum well sample at T …

Capture processes of an electronic wave packet traveling in a quantum wire into localized
states of an embedded quantum dot by means of phonon emission are studied in a quantum …

Quasi-one-dimensional carrier transport is studied in a single Al x Ga 1− x As/GaAs quantum
wire by combining two-color femtosecond pump and probe spectroscopy and near-field …

The dynamics of electronic excitations in a semiconductor quantum well after excitation with
spatially localized optical pulses (≤ 1 μm, 100 fs) is analyzed. Ballistic transport of electron …
