Date Time Researchers create ‘beautiful marriage’ of quantum enemies Cornell scientists have identified a new contender when it comes to quantum materials for computing and low-temperature electronics. Using nitride-based materials, the researchers created a material structure that simultaneously exhibits superconductivity – in which electrical resistance vanishes completely – and the quantum Hall effect, which produces resistance with extreme precision when a magnetic field is applied....

January 19, 2021 The path that leads to the next generation of high-power electronics is not long. But it needs to be wide. Very wide. A Cornell collaboration has found a way to grow a single crystalline layer of alpha-aluminum gallium oxide that has the widest energy bandgap to date – a discovery that clears the way for new semiconductors that will handle higher voltages, higher power densities and higher frequencies than previously seen. Provided The image at left shows the energy b...

December 21, 2020 The Earth’s soils contain more than three times the amount of carbon than is found in the atmosphere, but the processes that bind carbon in the soil are still not well understood. Improving such understanding may help researchers develop strategies for sequestering more carbon in soil, thereby keeping it out of the atmosphere where it combines with oxygen and acts as a greenhouse gas.
