Title: Voltage-dependent nonlinear resistance and manufacture thereof
Inventor: EDA KAZUO
IPC: H01C7/10
Filed: 1989-01-23
Abstract: PURPOSE:To enhance a limit voltage characteristic and a follow-current breaking performance and to prevent this resistance from being melted, short-circuited and destroyed by a method wherein a superconductor is formed at a part of a rare earth- alkaline earth-Cu oxide film. CONSTITUTION:An energy barrier 5 is formed at an interface between a ZnO layer 1 and a rare earth-alkaline earth-Cu oxide layer 2. Normally ZnO is an n-type semiconductor; accordingly, when a voltage is applied by using an electrode 3 as an anode, the energy barrier 5 is forward-biased; an electric current easily flows. On the contrary, when the voltage is applied by using an electrode 4 as the anode, the energy barrier 5 is reverse-biased. Accordingly, it is possible to obtain an element displaying an asymmetric voltage-dependent nonlinearity in which an electric current does not flow up to a definite voltage and is started to flow suddenly at the voltage or higher. Accordingly, a part in a superconducting state at the oxide layer 2 generates heat by the electric current; a temperature at the element part exceeds a superconducting critical temperature; a superconducting part is shifted to a superconducting state; a resistance is increased suddenly; thereby, a follow-current breaking performance is enhanced; it is possible to prevent the element from being melted, short-circuited and destroyed.
