PPT-II-VI Semiconductor Materials, Devices, and Applications

Lorelei Lewandowski 4202015 There are 7 IIVI semiconductor materials Because of their direct wide band gap energy they are becoming increasingly useful in optical applications While some of them have been around for many years research is still needed to determine the full potential of others The latest and greatest technology in the near future will most likely owe much of its success to these materials. The principles on which these devices operate current controlled by an electric field are very similar the primary difference being in the methods by which the control element is made This difference however results in a considerable difference in 8 Other Unipolar Junctions The metal semiconductor junction is the most studied unipolar junction be not the only one that occurs in semiconductor devices Two other unipolar junctions are the homojunction and the H www.dialog-semiconductor.com www.dialog-semiconductor.com A proven performerDECT is the de facto industry standard for cordless telephony.

Carbon . nanotubes. are small tubes of carbon fiber that are prized for their electrical, mechanical and thermal properties making them ideal for a variety of applications. CNTs small size and thermal properties make them ideal for future transistor and interconnect production providing a solution to the problem of Moore’s Law. In addition, CNT’s mechanical properties can be tied in with their electrical properties to produce a variety of sensors and related devices.. Professor Ronald L.
