1/1/2019· Appliions of silicon carbide and materials requirements Energy saving is one of the most critical problems of this century. In this context, improving the efficiency of electricity usage is of the highest importance, since electricity can be produced through nearly any energy generation process (e.g., steam, coal, solar arrays) and can travel vast distances without losing much energy.

Tunable Optical Chip Paves Way for New Quantum …

WASHINGTON — Researchers have created a silicon carbide (SiC) photonic integrated chip that can be thermally tuned by applying an electric signal. The approach could one day be used to create a large range of reconfigurable devices such as phase-shifters and tunable optical couplers needed for networking appliions and quantum information processing.

Crystal structures and the electronic properties of silicon …

The chemical formula of silicon-rich silicon carbide can be defined as nSi C:SiC which states n nuer of carbon atoms are replaced by n silicon atoms in an otherwise pristine silicon carbide phase. Our work mainly focuses on taking off the carbon atoms and substitute them with silicon to get structures having more silicon than the carbon atoms.

Scaling up photonic circuits offers route to quantum …

14/7/2020· In the MIT chiplets, the defects in the diamond lattice structure were replaced with germanium and silicon, with each center functioning as an atom-like emitter whose spin states can form a qubit. The quantum information represented by each qubit is then carried by photons of light that it …
