'Whispering gallery' effect controls electron beams with light

Fri, 06/05/2020 - 17:58
When you speak softly in one of the galleries of St Paul's cathedral, the sound runs so easily around the dome that visitors anywhere on its circumference can hear it. This striking phenomenon has been termed the 'whispering gallery' effect, and variants of it appear in many scenarios where a wave can travel nearly perfectly around a structure.

Filling the knowledge gap about the thermal properties of bismuth antimonide at the nanoscale

Fri, 06/05/2020 - 08:20
Bismuth antimonide (BiSb) is an important material in nanoelectronics as a topological insulator and as a thermoelectric material. However, some of its thermal properties are still mostly unknown at the nanoscale. This is an issue because in order for BiSb to exhibit its thermoelectric properties it has to be an alloy. But at the nanoscale, it is difficult to mix Bi and Sb. New findings provide the phase diagram of bismuth antimonide at nanoscale sizes for different types of morphologies like sphere, rod, wire, and film, thereby filling the knowledge gap about the thermal properties of BiSb at the nanoscale.
