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 …

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 …

All known superfluid and superconducting states of condensed matter are enabled by
composite bosons (atoms, molecules and Cooper pairs) made of an even number of …

The discovery of a two-dimensional electron gas (2DEG) at the LaAlO3/SrTiO3 interface has
resulted in the observation of many properties,,–not present in conventional semiconductor …

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

Moiré superlattices have emerged as an unprecedented manipulation tool for engineering
correlated quantum phenomena in van der Waals heterostructures. With moiré potentials as …

Bound electron–hole pairs—excitons—are light Bose particles with a mass comparable to or
smaller than that of the free electron. Since the quantum degeneracy temperature scales …

An accurate calculation of the exciton ground and excited states in AlGaAs and InGaAs
coupled quantum wells (CQWs) in an external electric field is presented. An efficient and …

In this Letter we report on lateral diffusion measurements of excitons at low temperature in
double quantum wells of various widths. The structure is designed so that excitons live up to …

We demonstrate experimental proof of principle for an optoelectronic transistor based on the
modulation of exciton flux via gate voltage. The exciton optoelectronic transistor (EXOT) …
