Cornell engineers have created a deep-ultraviolet laser using semiconductor materials that show great promise for improving the use of ultraviolet light for sterilizing medical tools, purifying water, sensing hazardous gases and enabling precision ph

A team of Cornell University engineers has built a deep-ultraviolet laser made up of semiconductor materials that demonstrate immense promise for enhancing the use of ultraviolet (UV) light for sanitizing water, sensing unsafe gases, and sterilizing medical tools, facilitating precision photolithography, and so on.

Researchers grew a thin film of one of the oldest known superconductors on top of a semiconductor, and for the first time measured the electronic properties of the junction between the two materials, paving the way for hybrid superconductor-semiconductor quantum devices.

A crystal structure that combines a semiconductor and superconductor is a tantalizing prospect to create energy-efficient computers, or quantum
