Taking a quantum leap from electronics to new …

Commonly known as carborundum, silicon carbide is a hard, transparent crystal used to make clutch plates, brake pads and bulletproof vests. Prior research had shown that silicon carbide could be modified to create color centers at room temperature. But this potential had not yet been made efficient enough to yield a quantum chip.

Coherent-sized quantum dots, dis-persed in a matrix of silicon carbide, nitride, or oxide, were fabried by precipitation of Si-rich material deposited by reactive sputtering or PECVD. Bandgap opening of Si QDs in nitride is more blue-shifted than that of Si QD in oxide, while clear evidence of quantum confinement in Si quantum dots in carbide was hard to obtain, probably due to many …

The Quantum Silicon approach harnesses electrons in collections of silicon atoms to represent, transmit, and create information. Our process uses virtually no current. The result is a new generation of computing circuits that are tiny, fast, and cool. • Silicon based …

Crystallization mechanism of silicon quantum …

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.

Engineering solid-state platforms for quantum …

In contrast, color centers are atomic-scale defects, which can be generated in site-specific loions and exhibit much smaller inhomogeneous broadening than quantum dots. We have thus worked to develop color centers in diamond and 4H-silicon carbide and their host materials into scalable quantum photonic platforms.
