Amorphous multi-component metallic films can be used to improve the performance of electronic devices such as resistors, diodes, and thin film transistors. An amorphous hot electron transistor (HET) having co-planar emitter and base electrodes provides electrical properties and performance advantages over existing vertical HET structures. Emitter and the base terminals of the transistor are both formed in an upper crystalline metal layer of an amorphous nonlinear resistor. The emitter and the base are adjacent to one another and spaced apart by a gap.
