We present results from a study of the nonlinear inter-modal coupling between different flexural vibrational modes of a single high-stress, doubly-clamped silicon nitride nanomechanical beam. Using the magnetomotive technique and working at 100 mK we

We use dynamic scanning capacitance microscopy to image compressible and incompressible strips at the edge of a Hall bar in a two-dimensional electron gas (2DEG) in the quantum Hall effect (QHE) regime. This method gives access to the complex local c

Insulating hexagonal boron nitride (hBN) is theoretically expected to undergo a crossover to a direct bandgap in the monolayer limit. Here, the authors perform optical spectroscopy measurements on atomically thin epitaxial hBN providing indications o

The light-matter interaction in bulk semiconductors is in the strong-coupling regime with hybrid eigenstates, the so-called exciton polaritons and phonon polaritons. In two-dimensional (2D) systems, the translational invariance is broken in the direc

Abstract We report the use of a novel atomic carbon source for the molecular beam epitaxy (MBE) of graphene layers on hBN flakes and on sapphire wafers at substrate growth temperatures of ~1400 °C. The source produces a flux of predominantly atomic

A brief review is given of earlier work on the crystallization of two-dimensional fluids formed from particles that interact via repulsive Coulomb forces. The two-dimensional fluid formed from ions trapped below the surface of superfluid 4He is descr

We have performed magnetic force microscopy at various temperatures utilizing piezoelectric quartz tuning forks as probes. Due to their large force constants (∼104N∕m), quartz tuning forks are intrinsically less sensitive to force gradients than

A series of conventional and novel (AlGa)As/GaAs two‐dimensional hole gas (2DHG) structures have been grown on (001) oriented surfaces. The samples were grown following an identical growth regime so as to render them comparable. The effects of vari
