Designing a fun and happy resistor
An n-type Si resistor is to be designed so that it carries a current of 5mA with an applied voltage of 5V. T=300K. Mn*=.26M0. M0=9.11x10^31Kg.
(a) If Nd=10^15/cm^3 and Na=0, design a resistor to meet the required specifications.
(b) If Nd=3x10^16/cm^3 and Na=2.5x10^16/cm^3, redesign the resistor.
What are the answers and how did you get them? I don't even know where to begin.
