Give a brief explanation of solid state semiconductor electronics.

(N/A) Solid state semiconductor devices and their junctions provide the capability to control both the quantity and the direction of charge carrier flow through them.
External excitations such as light,heat,or a small applied voltage can significantly alter the concentration of mobile charge carriers within a semiconductor.
In these devices,the generation and transport of charge carriers occur entirely within the solid material itself.
The primary devices in solid state electronics include:
$(1)$ Junction diode: $A$ device consisting of two electrodes.
$(2)$ Transistor: $A$ device consisting of three electrodes.
$(3)$ Integrated circuit $(IC)$: $A$ device containing numerous interconnected electronic components and electrodes.
