A realistic assessment of the prospect of silicon be replaced by other materials for IC applications

Abstract Silicon is the most common material used in semi-conductor. It can be to make single crystal silicon wafer. Though it has widest usage, high calorific value. Also, performance loss compared carbide and operating temperature relatively low gallium oxide. Luckily, there are several materials that could possibly replace silicon. The first one 2D semiconductor. prospective evaluation of semiconductors high. But now biggest problem low-resistance connections with them. second nitride. hardness, melting point stability. This makes a good for temperature, frequency power devices. However, excellent property brings cost. disadvantage prevents nitride widely used. last graphene. strong electrical conductivity, ultra-high strength, properties, electron interaction. higher carrier mobility than While every coin two sides, producing graphene on large scale difficult expensive. Besides, highly reactive oxygen heat. What’s more, zero band gap nearly impossible become semi-conductor material. Even though many methods opening bandgap, these still bring inevitable drawbacks. All all, problems solved when new integrated circuit applications.
