Abstract Large-scale two-dimensional (2D) moiré superlattices are driving a revolution in designer quantum materials. The electronic interactions in these superlattices, strongly dependent on the periodicity and symmetry of the moiré pattern, criti

Abstract Single spin-defects in 2D transition-metal dichalcogenides are natural spin-photon interfaces for quantum applications. Here we report high-field magneto-photoluminescence spectroscopy from three emission lines (Q1, Q2, and Q*) of He-ion ind

Nucleation control of self-assembled quantum dots is challenging. Here, the authors employ conventional molecular beam epitaxy to achieve wafer-scale density modulation of high-quality quantum dots with tunable periodicity on unpatterned substrates.

Light emitters can be induced in transition metal dichalcogenides by defect engineering, but challenges remain in their controlled spatial positioning. Here, the authors irradiate monolayer MoS2 with a sub-nm focused helium ion beam to deterministica

We report magneto-optical spectroscopy of gated monolayer MoS_{2} in high magnetic fields up to 28T and obtain new insights on the many-body interaction of neutral and charged excitons with the resident charges of distinct spin and valley texture. Fo

Abstract We report on non-conventional lasing in a photonic-crystal nanocavity that operates with only four solid-state quantum-dot emitters. In a comparison between microscopic theory and experiment, we demonstrate that irrespective of emitter detun

Although nanolasers have been an active field of research for over a decade, mode-locking on the nanoscale has not been achieved yet. Here, Mayeret al. show that semiconductor nanowire lasers can emit pairs of phase-locked picosecond pulses when the

We demonstrate that optically active emitters can be locally generated by focusing a He-ion beam onto monolayer WS2 encapsulated in hBN. The emitters show a low-temperature photoluminescence spectrum, which is well described by an independent Boson m
