The PN Junction Diode George W. Neudeck
Publisher: Prentice Hall

A Diode is a unidirectional device permitting the easy current flow in one direction but resisting the flow in opposite direction. Introduction: we have developed a PN junction diode transistor kit. A diode is one of the simplest semiconductor devices, which has the characteristic of passing current in one direction only. A semiconductor diode is simply a P-N junction with connecting leads or terminals on its two sides. View the complete course: http://ocw.mit.edu/2-57S12 Instructor: Gang Chen. MIT 2.57 Nano-to-Micro Transport Processes, Spring 2012. To understand how a pn-junction diode works, begin by imagining two separate bits of semiconductor, one n-type, the other p-type. IQ1 = I_ref Now what should I do next? The following experiments are possible with this kit. Find Vo1: Vo1 = R4/(R3+R4) *Vin - 0.7. I got stuck with this problem: Here Q1 and Q2 behave like p-n junction diodes.
