Penn State researchers develop kink-state switch for electrical conduction control in semiconducting materials, potentially advancing quantum electronics.

Penn State researchers have developed a kink-state switch, controlling electrical conduction pathways at semiconducting material edges. This breakthrough could lead to quantum electronics advancements, including advanced sensors, lasers, and quantum computers, by regulating electron flow in quantum systems. The researchers' next goal is to demonstrate how electrons can behave as coherent waves on kink-state highways.
