Neamen's Semiconductor Physics and Devices, Third Edition. deals with the electrical properties and characteristics of semiconductor materials and devices. The goal of this book is to bring together quantum mechanics, the quantum theory of solids, semiconductor material physics, and semiconductor device physics in a clear and understandable way.

This book is an introductory explication on the theme of knot and link invariants as generalized amplitudes (vacuum-vacuum amplitudes) for a quasi-physical process. The demands of the knot theory, coupled with a quantum statistical frame work create a context that naturally and powerfully includes an extraordinary range of interelated topics in topology and mathematical physics...(展开全部)

Since its birth in Poincaré's seminal 1894 "Analysis Situs", topology has become a cornerstone of mathematics. As with all beautiful mathematical concepts, topology inevitably — resonating with that Wignerian principle of the effectiveness of mathematics in the natural sciences — finds its prominent role in physics. From Chern–Simons theory to topological quantum field theory, ...(展开全部)

在准备本书第6版时，我想将一些对电力系统有较大影响的新内容介绍给大家，其中有以下5部分内容。 第13章、12.23～12.26节介绍了双馈感应电机的原理与特性。该电机的调速可通过在定子加固定频率交流电，而在转子通入可变频率交流电来实现，故名为“双馈”。双馈电机原来用作变速电动机来驱动大型水泵等负载，现在，该电机在风力发电中作为双馈发电动机使用。由于风力发电的重要性，有必要在本书中介绍这种特殊的电机。 第21章、21.45～21.51节对PWM的相关内容作了重要的修改，增加了新的内容及图片。 第23章介绍了几种电动机调速的电子控制方法。23.31～23.40节特别介绍了直接转矩控制（DTC）方法，与应用PWM及矢量控制方法不用，DTC使用了砰砰控制法，其对速度及转矩的控制与其他方法不同，该章根据感应电机原理，对此做了直观的分析。 第24章、24...(展开全部)

菲利普·瑞弗（Philip Reeve） 1966年出生于英国的布莱顿，紧邻伦敦的一个美丽的海滨城市。那里冬天寒冷得像童话世界，夏天美得像天堂。 他先后在剑桥艺术和技术学院以及布赖顿理工学院学习插图。他在书店工作多年，因为作恐怖历史小说的插图而略有名气。没人相信他从五岁就开始写作，而立之年才大器晚成，终于凭青少年文学处女作《致命引擎》（Mortal Engines）一书，征服了挑剔的英国编辑和读者，走红英伦。
