What is Semiconductor Physics? Almost all modern electronic devices depend on silicon chip. Silicon chips are produced from semiconductor materials. Semiconductors (also known simply as integrated circuits, microelectronic chips, or computer chips) are, therefore, tiny electronic devices (based primarily on silicon or germanium). In other words, a semiconductor is a material which is neither a good conductor nor a goodinsulator. Examples: Germanium, silicon, gallium-arsenide, gallium-phosphide.
