Van der Waals (vdW) heterostructures based on transition metal dichalcogenides (TMDs)
generally possess a type-II band alignment that facilitates the formation of interlayer excitons …

Abstract The study of Bose–Einstein condensation effects in photonic systems has revealed
a rich phenomenology related to spontaneous coherence generation in driven-dissipative …

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

If bosonic particles are cooled down below the temperature of quantum degeneracy, they
can spontaneously form a coherent state in which individual matter waves synchronize and …

Efficient signal communication uses photons. Signal processing, however, uses an optically
inactive medium, electrons. Therefore, an interconnection between electronic signal …

We review recent progress on Bose–Einstein condensation (BEC) of semiconductor
excitons. The first part deals with theory, the second part with experiments. This Review is …

Indirect excitons can be controlled by voltage, can travel over large distances before
recombination, and can cool down close to the temperature of semiconductor crystal lattice …

Photonic and optoelectronic devices may offer the opportunity to realize efficient signal
processing at speeds higher than in conventional electronic devices. Switches form the …

We present the first reliability study of InAs/GaAs self-assembled quantum dot lasers
epitaxially grown on Ge/Si substrates. Some devices maintain lasing oscillation after more …

Long lifetimes of spatially indirect excitons (IXs), also known as interlayer excitons, allow
implementing both quantum exciton systems and long-range exciton transport. The van der …
