Graphene in van der Waals heterostructures and transistors

Graphene tunnelling transistors are made by sandwiching a nanometre-thick barrier layer of hexagonal boron nitride (hBN) between two monolayer graphene electrodes.  The tunnel current is controlled by the bias voltage…

Atomic and electronic structure in van der Waals heterostructures

Two-dimensional materials (2DM) have strong in-plane bonding, but typically only weak van der Waals interactions with neighbouring material. It is this anisotropy which allows them to be isolated as layers,…

Polariton Lattices: a new platform for quantum simulators

Finding the ground state of physical systems is the natural quantum analogue of classical constraint satisfaction problems that are mapped into various optimization problems in technology and life sciences. Most…

High quality solid-state spin-photon interfaces

Optically active spins confined in solids, such as semiconductors and diamond, provide interesting and rich physical systems. Their inherently mesoscopic nature leads to a multitude of dynamics within the solid…

Quantum state control in single quantum dots

Quantum dots have been investigated intensively for last two decades to implement solid state quantum information processing because of the long coherence time, particularly for spin-based quantum bits. Photocurrent spectroscopy…
