Question
Two semiconductor materials X and Y shown in the given figure, are made by doping germanium crystal with indum and arsenic respectively. The two are joined end to end and connected to a battery as shown.
  1. Will the junction be forward biased or reverse biased?
  2. Sketch a V-I graph for this arrangement.
✓

Answer

(If X and Y are correctly identified but the identification of biasing is incorrect or not given at all, award.)
$(\text{X}\rightarrow\text{p} \text{Type})$
$(\text{Y}\rightarrow\text{n} \text{Type})$
  1. Reverse biased.
  2. Graph:
