QUESTION 3 What current in microamps do we get with an ideal abrupt junction silicon diode with (100 micron)M2 area and doped with acceptors at 6.9 1015/cc, 1000 times more donor doping, and forward bias of 0.52 V. Assume e- & e+ mobilities of 1500 & 500 cmA2/(V*s), and minority carrier lifetimes of 1 microsecond. Vt-0.02585V, Answer should be to two significant digits with fixed point notation.

Pittman Company is a small but growing manufacturer of telecommunications equipment. The company has no sales force of its own; rather, it relies completely on independent sales agents to market its products. These agents are paid a sales commission of 16% for all items sold. Barbara Cheney, Pittman’s controller, has just prepared the company’s budgeted income statement for next year. The statement follows: Pittman Company Budgeted Income Statement For the Year Ended December 31 Sales $ 20,800,000 Manufacturing expenses: Variable...

HDT Truck Company HDT Truck Company has been located in Crown Point, Indiana, since 1910. Its only products— large trucks—are built to individual customer specifications. The firm once produced automobiles but dropped out of the auto business in 1924. The firm nearly went out of business in the late 1930s, but by 1940 its fortunes were buoyed by receipt of several military contracts for tank retrievers—large-wheeled vehicles that can pull a disabled tank onto a low trailer and haul it...

Physics Lab Assignment This particular discovery is also an example of how those who deserve an award sadly are not always the ones who receive it. Read the following passage focusing your attention on the scientific procedures and scientific abilities you have been developing throughout the course. The discovery of pulsars –rotating neutron stars that generate regular pulses of radiation at their spin rate- was fortuitous. A group of astrophysicists from Cambridge University lead by Anthony Hewish was looking for...
