TL;DR: In this article, the photoresponse signal can be tuned in both magnitude and sign with a voltage applied to the back gate of the hybrid graphene-PbS quantum dot devices and is related to the derivative of the transfer characteristics of the graphene channel.

TL;DR: This work has performed optical spectroscopy in single CsPbBr3 nanoplatelets and observed a single photon emission without blinking and the PL emission exhibits excitonic fine structure peaks similar to what has been previously observed in nanocubes.

TL;DR: In this article, a non-Hermitian topological invariant arising from spectral degeneracies (exceptional points) in the momentum space of exciton polaritons was measured.

TL;DR: This work demonstrates, for the first time, optically pumped lasing from the GaNAs shell of a single GaAs/GaNAs core/shell NW, and represents the first step toward development of room-temperature infrared NW lasers based on dilute nitrides with extended tunability in the lasing wavelength.

TL;DR: By exploring the out-of-plane spin texture, spin injection from GaAs to TI and its significant contribution to the surface current are demonstrated and pave the way to not only intriguing new physics but also enriched spin functionalities by integrating TI with conventional semiconductors, such that spin-enabled optoelectronic devices may be fabricated in such hybrid structures.
