V-pits on the surface of an InGaN LED (left) scatter light into the device’s active layers, known as quantum wells (QWs – right). Credit: American Chemical Society.
Standard light-emitting diodes (LEDs) used for home lighting can now transmit data more rapidly between electronic devices, thanks [...]

Cubic SiC films (3C–SiC) were deposited on (111) Si substrates by a vapor–liquid–solid tri-phase growth method. In such a process a thin copper layer, which was evaporated on the Si substrate prior to the growth, was melted at high temperature as the flux and [...]
