March’s ‘Paper of the Month’ comes from Dr Yong Zhang and Dr Liqin Su at the University of North Carolina Charlotte (UNCC).

In their paper “Temperature coefficients of phonon frequencies and thermal conductivity in black phosphorous layers” (Applied Physics Letters, 2015), Zhang and Su investigate the vibrational properties and electron-phonon interactions of black phosphorous, as well as how epitaxial or supporting substrates can impact the properties of a 2D material which is often presumed to have weak bonding with the substrate.

Black phosphorous is a particularly promising material due to its layer-dependant band gap, meaning it can function as a semi-conductor – essentially, it can be switched on and off. Its application in new nanotechnologies could give rise to a range of high performance electronic and optoelectronic devices.
