Document Summary

1. 013 x 105 pa; 1 pa = 1 j/m3, mass density sio2 = 2. 65 g/cm3. 5 pts. each: fill in the associated si units for the following quantities: Constant relating kinetic energy and gas temperature; r = kb x (avagadro"s number: for an activated process described by an arrhenius rate coefficient (i. e. k = k0 exp(- In reality, gas molecules do not have a well-defined diameter and experience van der waals attraction at longer separation distances and repulsion at shorter distances. N-type dopants are electron donors; these increase electron centration. P-type dopants are electron acceptors; these increase the hole concentration. Mosfet as a depletion-mode device they are normally on", and are turned off" by applying a voltage to the gate and depleting the concentration of majority charge carriers in the channel. Draw an n-channel depletion-mode mosfet and label the component parts with names and compositions.
