Room Temperature Quantum Light from Colour Centres in III-Nitride's

Speaker: Sam Bishop (ABennett)
Date: Friday 7 May 2021
Time: 15:00
Venue: Zoom

A device that is able to produce single photons is a fundamental building block for a number of quantum technologies. Significant progress has been made in engineering quantum emission in the solid state, for instance, using semiconductor quantum dots as well as defect sites in bulk and two-dimensional materials. To date, only a handful of solid state devices can emit single photons at room temperature. In this talk, I will discuss the recently discovered family of room temperature quantum emitters in III-Nitride materials, specifically Gallium Nitride (GaN) and Aluminium Nitride (AlN). In addition, I will discuss how we aim to drastically enhance a fundamental limitation of these emitters: the number of photons that we are able to extract from the high refractive index semiconductors.
