半导体基本原理、吸收、直接跃迁、间接跃迁、辐射、发光复合、非发光复合、施子、受子、激子、声子、光子、恒化子。 - Cdse , a ii - vi compound with direct transition , wide - band - gap and high atomic number ( 48 , 34 ) , is regarded as a new effective materials for room temperature nuclear radiation detectors and photoconductive devices , and can be used in many fields
Prince提出的优良室温核辐射探测器材料必须具备的要求，因而被认为是制备室温核辐射探测器的最有前途的新材料之一，可广泛应用于探矿、无损检测、核医学、环境监测、军事和空间宇航技术等领域。 - This work was supported by the state science and technology ministry of p . r . china under the contact no . g20000683 - 06 , and by the national natural science foundation of p . r . china under grant no . 60046001 . gallium nitride is one of the 3rd generation semiconductor materials . from 1990 ' s , gan has attracted more and more attention and advanced rapidly , mainly due to its direct transition , wide band gap ( ~ 3 . 4ev ) and other excellent characters
Gan是直接跃迁的宽带隙材料，具有禁带宽度大( 3 . 4ev ，远大于si的1 . 12ev ，也大于sic的3 . 0ev ) ，电子漂移饱和速度高，介电常数小，导热性能好等特点，在光电子器件和电子器件领域有着广泛的应用前景。 - Birth - death processes is a greatly important kind of markov processes . however , in most real applications , the processes with state space e = { 0 , 1 , 2 , - - - } can make direct transitions from a state i not only to one of its nearest neighbor states i ( if / > i ) and i + l , but also to state 0 , from 0 to any state / . therefore , we need to consider a new model ( extended birth - death processes ) with the special property in which catastrophes is imposed to ordinary birth - death processes
在马尔可夫过程中，生灭过程无疑是其中极为重要的一类，但由于在许多现实模型中，具有状态空间e = { 0 ， 1 ， 2 ， … }的过程从任一状态i出发，下一步不但能到达相邻的状态i + 1或i - 1 ，且能回到初始状态0 ，从0出发可以达到任意状态，这时我们需要将一般生灭(拟) q -矩阵，推广到更一般的具有更广泛的应用背景及理论研究价值的情况。
