Lab talk

Studies of defects in boron nitride reveal useful properties for devices

First-principles calculations of defects in boron nitride highlight properties that may be used in nanoelectronics, spintronics and electromechanical devices

Topological insulators under a terahertz field

Linearly polarized terahertz-field induced anisotropic conductivity reveals oscillation and phase transition behaviour in topological insulators.

Probing causality with tunable Fermi gas condensates

We develop a new formalism to study emergent analogue space-times from condensates of cold Fermi atoms, where phonons, the particles of sound, play the role of light.

Does surface roughness really matter in nanowires?

Nanowire geometries and surface properties should be taken into account when designing high-performance devices.

Graphene nanonets make biological sensors

Selectively assembled V2O5 nanowires act as a shadow mask for producing graphene nanonet patterns over a large surface area.
