The Discovery Of The Electron The electron was discovered in 1895 by J.J. Thomson in the form of cathode rays‚ and was the first elementary particle to be identified. The electron is the lightest known particle which possesses an electric charge. Its rest mass is Me <approximately equal> 9.1 x 10 -28 g‚ about 1/1836 of the mass of the proton or neutron. The charge of the electron is -e = -4.8 x 10^-10 esu <elec trostatic unit). The sign of the electron’s charge is negative by convention‚ and

SINGLE ELECTRON TRANSISTOR SEMINAR ABSTRACT A single-electron transistor consists of a small conducting island connected to the source and drain leads by tunnel junctions and connected to one or more gates. The nanometre scale conductive island is embedded in an insulating material. Gate signals are capacitive coupled to the island. Two gate signals can be applied to the island out of which one is optional. Here‚ only one electron can tunnel from source to drain. The processes
