Already it is clear that to achieve terahertz speeds of semiconductor devices will only be possible after transfer to other technology than CMOS. The laboratories have long been studying the effect of quantum tunneling, when electrons are transferred from the metal to metal in the so-called MIM-transitions (metal-insulator-metal). This is a three-layer structure where the two metals is an insulator. They played the role of diodes, a current is passed in one direction and locking in the back. A quantum effect is that the transition from metal to metal the electrons do not react with an insulator which reduces heat generation and consumption of the device.
Work on the development of effective MIIM-structures are maintained for a long time, and the theoretical description of MIMIM-transistor was a half century ago. In general, it is about working with very small currents. For example, such diodes can generate electricity from panels that absorb infrared radiation. Yes, the solar panels will be able to work in complete darkness. Related Products :
