Single Electron Transistor

Single Electron Transistor is a future technology that is going to be revolutionize the current digital data storage technologies. As the name suggest it uses a single electron to carry or amplify current.Its capability makes it very useful for the high operating speed and low power consumption.

This  single electron transistor uses the controlled electron tunneling to amplify the current. It is made up of  two tunnel junctions to share a common electrode. This tunnel junction structure consist of the two metal pieces. These metal pieces are separated by an insulator of near about 0.998 nm length.

Some of its future application are as follows:
1). Ultra-sensitive Microwave detector
2). Super-sensitive Electrometer
3).Charge Sensor
4).Single Electron Spectroscopy etc
