摘要：A tunnel diode having a generally rectangular junction area in the 10. sup.-10 to10.sup.-11 cm.sup.2 range formed in a quasi-planar structure of a first metal, an oxide ofthe first metal and a second metal. The first metal may be tantalum or other similarlyslow oxidizable metals. The second metal may be selected from a group also includingtantalum. For a symmetrical junction, the first and second metals are the same, however,for an asymmetrical junction the first and second metals are different. To reduce thediode series electrical and thermal resistance, a gold layer is deposited over the first andsecond metals. The gold layer over the first metal is deposited everywhere except at orwithin a few microns of the junction. The device provides a small junction area and alsonegligible parasitic shunt capacitance which are necessary for efficient room temperatureoperation at frequencies in the submillimeter to optical region. Direct and heterodynedetection in the 10 microns region has been successfully achieved with these devices.
