Extracted text: 2) A Schottky diode made from n-type GaAs has a 0.7V turn-on voltage. It has previously been characterized and found to have a contact resistance of 35 Q. This diode is connected in series with a Nichrome thin film resistor with a resistivity of 112x10-6 2 cm. The resistor is 100µm wide, 1mm long and is 2240Å thick. With 0.785V across the resistor/diode pair the current measured is 630µA. A visual inspection of the resistor and diode indicate no processing abnormalities. a) What is the expected value of the current measured? b) If there are any differences in the measured and expected value suggest the cause and the solution.
