Some low-coordination materials, including water, silica, and silicon, exhibit polyamorphism, having multiple amorphous forms. However, the microscopic mechanism and kinetic pathway of ...

Solar cells and computer chips need silicon layers that are as perfect as possible. Every imperfection in the crystalline structure increases the risk of reduced efficiency or defective switching ...

Scientists have used pressure with a twisting shear to permanently deform silicon, an important material for electronics. The resulting changes in silicon's microstructure produce material phases that ...

Associate Professor Yuichiro Matsushita of Materials and Structures Laboratory, Institute of Science Tokyo, Mitsubishi Electric Corporation, Associate Professor Takahide Umeda of Institute of Pure and ...

Scientists uncovered rare hexagonal silicon forms (2H, 4H, 6H) created by stress and heat, challenging assumptions about this key electronic material. This is not the first time hexagonal silicon has ...
