Light-matter interactions lie at the heart of condensed matter physics, providing physical insight into material behaviour while enabling the design of new devices. Perhaps this is most evident in the push to develop quantum information and spintronic technologies. On the side of quantum information, engineered light-matter interactions offer access to and control of quantum states. Meanwhile...

The etching of compound semiconductors with atomic level resolution is of high interest to technologies addressing the fabrication of low-dimensional devices, the tunability of their optoelectronic properties and the precise control of device surface structure. We have developed an innovative method of digital photocorrosion (DIP) for shallow (< 200 nm) etching of GaAs/AlGaAs...

Valley polarization associated with the occupancy in energy degenerate but quantum mechanically distinct valleys in the momentum space resembles the spin polarization in many aspects, including the valley magnetic moment, optical selection rule, and valley hall effect. Atomically thin transition metal dichalcogenides (TMDs), a class of honeycomb-like layered materials with broken inversion...

A recent study on the Weyl semimetal tantalum arsenide showed that it has an unusually large second-order nonlinear optical susceptibility [1]. Subsequently, models that connect the band-structure geometry and the nonlinear susceptibility were established to explain this anomaly [2],[3]. Here we study second harmonic generation (SHG) in another acentric semimetal, tungsten telluride...

Two dimensional materials refer to a class of crystals that are atomically thin. Since the isolation of the first 2D material, graphene, the study of such low dimensional systems has attracted widespread attention with the goals of advancing fundamental knowledge and of facilitating the development of next-generation optoelectronic technologies. Crucial to realizing translations to...
