A New Way to Turn Electricity Into Light

By slowing down light to a speed slower than flowing electrons, scientists have developed a new way to turn electricity into light. When an airplane begins to move faster than the speed of sound, it creates a shockwave that produces a well-known “boom” of sound. Now, researchers at MIT and elsewhere have discovered a similar […]

Switchable Material Could Enable New Memory Chip Design

A new thin-film material whose phase and electrical properties can be switched between metallic and semiconducting could lead to new memory chip designs. Two MIT researchers have developed a thin-film material whose phase and electrical properties can be switched between metallic and semiconducting simply by applying a small voltage. The material then stays in its […]
