First-principles computation of boron-nitride-based ultrathin UV-C light emitting diodes
Short wavelength ultraviolet (UV-C) light deactivates DNA of any germs, including multiresistive bacteria and viruses like COVID-19. Two-dimensional (2D) material-based UV-C light emitting diodes can potentially be integrated into arbitrary surfaces to allow for shadow-free surface disinfection. In...

| description | Short wavelength ultraviolet (UV-C) light deactivates DNA of any germs,
including multiresistive bacteria and viruses like COVID-19. Two-dimensional
(2D) material-based UV-C light emitting diodes can potentially be integrated
into arbitrary surfaces to allow for shadow-free surface disinfection. In this
work, we perform a series of first-principles calculations to identify the core
components of ultrathin LEDs based on hexagonal boron nitride (hBN). The
electrons and holes are predicted to be confined in multiple quantum wells
(MQWs) by combining hBN layers with different stacking orders. Various p- and
n-doping candidates for hBN are assessed, and the relative p- and n-type metal
contacts with low Schottky barrier heights are identified. The findings are
summarized in a concrete UV-C LED structure proposal. |
