A Semiconductor temperature

  1. Jul 30, 2017 #1
    Hello
    I have got a question and i dont know the answer. Please help me.
    I have a n doped semiconductor. How does the number of conduction electrons depends on temperature and compare the situation to an intrinsic semiconductor?
    Do i look at the intrinsic density, because when it is n doped than n is much bigger than p and the multiplication will be dominated by n. Then i would know the temperature dependence for intrinsic T^3/2 *exp ?
    Thanks in advance

    The answer is rather long. I'd suggest reading John McKelvey's "Solid State and Semiconductor Physics". He fully develops how electron and hole concentration vary with temperature.

    Try to read about vacuum diode, it uses heat depend transfer. Look also at semiconductor diode to have more reliable info.
