Which of the following is not true about depreciation? Group of answer choices It is a non-cash expense. It affects corporate taxes. It does not affect net income. All of these are true.
In class Monday we established that the number density of free electrons in silicon was 1.09E+16 electrons per cubic meter. Now calculate the number of free electrons per silicon atom. The density of silicon is 2.33 Mg/m3 ; the atomic mass of silicon is 28.085 g/mole. Consider silicon which has a band gap of 1.11 eV and a measured conductivity of 0.00034 /ohmm at 300K. Its electron mobility is 0.145 m^2/(V x sec) and its hole mobility is 0.050 m^2/(V...
