Abstract
An electronic part is disclosed which is furnished with an artificial super lattice obtained by alternately superposing a substance of good conductivity formed of a compound between one element selected from among the elements belonging to the transition elements of Groups 3A to 6A and the rare earth elements and an element selected from among boron, carbon, nitrogen, phosphorus, selenium, and tellurium or a compound between oxygen and a transition metal element selected from among the elements of Group 7A and Group 8 and an insulating substance formed of a compound between a simple metal element selected from among the elements belonging to Group 1A, Group 2A, and Groups 1B to 4B and an element selected from among carbon, nitrogen, oxygen, phosphorus, sulfur, selenium, tellurium, and halogen elements in thicknesses fit for obtaining a quantum size effect. The artificial super lattice possesses a barrier layer formed of an insulating substance and an electrode layer formed of a substance of good conductivity and disposed in contact with the barrier layers.
