I also realized which was the simple "electromagnetic" explanation to the fact that if you put a voltage meter across a PN junction diode you get 0 V. When the diode is not forward biased, the built-in potential stops the carriers in the neutral regions from diffusing and entering the dep...
Contrast is observed as the sample is heated to 673K, and in a separate experiment, as the junction is forward and reverse biased. Results presented here show a dependence of the contrast on the junction built-in voltage. This provides some support for patch fields as the contrast mechanism....

A new voltage reference with output dependent upon the threshold voltage of an NMOS transistor is introduced. A low temperature coefficient is achieved by using a pn-junction PTAT current generator to compensate for the negative temperature coefficient of the threshold voltage. Implemented in a standar...
