For undergraduate electrical engineering students or for practicing engineers and scientists interested in updating their understanding of modern electronics One of the most widely used introductory books on semiconductor materials, physics, devices and technology, Solid State Electronic Devices aims to: 1) develop basic semiconductor physics concepts, so students can better understand current and future devices; and 2) provide a sound understanding of current semiconductor devices and technology, so that their applications to electronic and optoelectronic circuits and systems can be appreciated. Students are brought to a level of understanding that will enable them to read much of the current literature on new devices and applications. Teaching and Learning Experience This program will provide a better teaching and learning experience-for you and your students. It will help: *Provide a Sound Understanding of Current Semiconductor Devices: With this background, students will be able to see how their applications to electronic and optoelectronic circuits and systems are meaningful.*Incorporate the Basics of Semiconductor Materials and Conduction Processes in Solids: Most of the commonly used semiconductor terms and concepts are introduced and related to a broad range of devices. *Develop Basic Semiconductor Physics Concepts: With this background, students will be better able to understand current and future devices.

Protection of DIP has always been a concern, and there has never been a perfect solution. To manage the rights of the DIP and to avoid digital piracy, we need a system that prevents unauthorized access to digital content and manages content usage rights. DRM is still at the nascent state, so, there are very limited number of DRM based solutions available in the market. Current DRM researches remain confined within the areas like music services and E-book publishing. There is no DRM based solution in E-commerce transaction system for protecting DIP transacted over the Internet. Thus, in current E-commerce transaction model there is a strong justification to develop a DRM based DIP protection model called Digital Intellectual Property Rights Management System (DIPRMS) that is expected to become an effective tool in overcoming all functional deficiencies and that may be used safely to transact DIP in E-commerce system. Object oriented modeling is the latest trend of software engineering towards development of high quality and secure software. Proposed object oriented analysis and design of DIPRM based transaction system of E-commerce with the help of Unified Modeling Language (UML).
