Phonon symmetries in hexagonal boron nitride probed by incoherent light emission

Antenna-coupled photon emission from hexagonal boron nitride tunnel junctions.

The ultrafast conversion of electrical signals to optical signals at the nanoscale is of fundamental interest for data processing, telecommunication and optical interconnects. However, the modulation bandwidths of semiconductor light-emitting diodes are limited by the spontaneous recombination rate of electron-hole pairs, and the footprint of electrically driven ultrafast lasers is too large fo...

Sub-Angstrom Edge Relaxations Probed by Electron Microscopy in Hexagonal Boron Nitride (h-BN)

Subangstrom edge relaxations probed by electron microscopy in hexagonal boron nitride.

Theoretical research on the two-dimensional crystal structure of hexagonal boron nitride (h-BN) has suggested that the physical properties of h-BN can be tailored for a wealth of applications by controlling the atomic structure of the membrane edges. Unexplored for h-BN, however, is the possibility that small additional edge-atom distortions could have electronic structure implications critical...
