Silicon carbide is a promising platform for single photon sources, quantum bits (qubits), and nanoscale sensors based on individual color centers. Toward this goal, we develop a scalable array of nanopillars incorporating single silicon vacancy centers in 4H-SiC, readily available for efficient interfacing with free-space objective and lensed-fibers. A commercially obtained substrate is

Light passes through a colour filter array to be detected by the quantum dots in the QuantumFilm layer. According to the company, the higher positioning of the photosensitive layer allows the QuantumFilm pixel to detect more photons, store more electrons, and reproduce colors more accurately than a silicon device - all with a thinner camera module.

We have investigated the crystallization process of silicon quantum dots (QDs) iedded in hydrogenated amorphous Si-rich silicon carbide (a-SiC:H) films. Analysis reveals that crystallization of silicon QDs upon thermal annealing of the samples can be explained in terms of bonding configuration and evolution of microstructure.

1. Introduction Quantum dot (QD) has been gaining significant momentum in the photoluminescent field because of its band gap tunability, strong light harvesting capability and large surface to volume ratios [, , , , , ]. 0D photoluminescent (PL) QDs could be prepared by chopping the 2D transition metal carbide nanosheets to smaller than 10 nm, due to the quantum confinement and edge effect [7,8].
Under the continued supervision of Professor Kortshagen, he contributed to the field by developing a novel synthesis technique for the production of silicon quantum dots. His Ph.D. work resulted in the publiion of several peer-reviewed articles and in the filing of two patent appliions.
Quantum dots are tiny particles or nanocrystals of a semiconducting material with diameters in the range of 2-10 nanometers (10-50 atoms).Quantum dots can emit any color of light from the same material simply by changing the dot size. Additionally, because of
Millions of quantum processors will be needed to build quantum computers, and the new research demonstrates a viable way to scale up processor production, he and his colleagues note. Unlike classical computers, which process and store information using bits represented by either 0s and 1s, quantum computers operate using quantum bits, or qubits, which can represent 0, 1, or both at the same time.

Here, we experimentally demonstrate the formation of silicon carbide (SiC) nanocrystals with wide size distribution (70–700 nm) by irradiation of carbon layers deposited on silicon wafers with ultrashort laser pulses of 42 fs pulse duration with 1 kHz repetition rate.
The frequency emitted by quantum dots can be tuned by varying the size of the dots, their shape and material used for their construction. The figure-1 depicts structure of Quantum dots. Usually Cadmium Selenide is used as inner core and Cd 1-x Zn x S outer shell, coated in silica to avoid oxidation.
