Ultraviolet Single Photon Detection With Geiger-Mode …

We report 4H-SiC avalanche photodiodes operated in Geiger mode for single photon detection at 265 nm. At room temperature, the single photon detection efficiency is 14% with a dark count probability of 1.7 x 10<sup>-4</sup>. Since the external quantum efficiency is 21% at 265 nm, it follows that 65% of the absorbed photons are counted as avalanche events. The jitter of the

Single-photon sources in diamond, silicon carbide and …

Telecom wavelength single photon sources have been found in both gallium nitride and silicon carbide. More importantly, those emitters work even at room temperature and are promising for quantum key distribution appliions in the future.

Single-photon emitter holds promise for quantum info …

"Ideally, a single photon emitter will provide both room-temperature operation and emission at telecom wavelengths, but this has remained an elusive goal. Up to now, materials that could act as single photon emitters in these wavelengths had to be cooled to liquid helium temperatures, rendering them much less useful for ultimate appliions or scientific purposes," he said.

Tech: A ‘recipe book’ that creates color centers in silicon …

While some materials considered for quantum computing require cryogenically low temperatures, color centers in SiC can emit at room temperature. As the push to create increasingly smaller devices continues into atom-scale sensors and single-photon emitters, the ability to take advantage of existing SiC integrated circuit technology makes the material a standout candidate.

For example, researchers at the Moscow Institute Of Physics And Technology have begun using silicon carbide create a system to release single photons in aient i.e. room temperature conditions. To maintain security quantum computers need to output quantum bits – essentially single photons.

Vanadium spin qubits as telecom quantum emitters in …

Solid-state quantum emitters with spin registers are promising platforms for quantum communiion, yet few emit in the narrow telecom band necessary for low-loss fiber networks. Here, we create and isolate near-surface single vanadium dopants in silicon carbide (SiC) with stable and narrow emission in the O band, with brightness allowing cavity-free detection in a wafer-scale material. In

Temperature dependence of avalanche breakdown for …

Uniform avalanche breakdown in 4H silicon carbide appears to have a positive temperature coefficient, in contrast to the 6H polytype, where the temperature coefficient is negative. The influence of deep levels on avalanche breakdown in epitaxial diodes is of minor importance for uniform breakdown, but appears to be significant for breakdown through microplasmas.
