A new quantum switch for electronics

A Russian physicist and his international colleagues studied a quantum point contact (QCP) between two conductors with external oscillating fields applied to the contact. They found that, for some types of contacts, an increase in the oscillation frequency above a critical value reduced the current to zero—a promising mechanism that can help create nanoelectronics components. This research supported by the Russian…
