\nGraph (a) correctly represents the current (I) \u2013 voltage (V) variation for a rectangular piece of a semiconductor wafer under conditions where it behaves ohmically.
\n<\/section>\n
\nWhile semiconductors are known for non-linear behavior in devices like diodes and transistors, a simple rectangular piece of bulk semiconductor material with ohmic contacts behaves like a resistor. According to Ohm’s Law, the current (I) flowing through a resistor is directly proportional to the applied voltage (V) (V = IR or I = V\/R), provided the temperature is constant. This relationship is represented by a straight line passing through the origin on an I-V graph. Graph (a) shows this linear relationship, indicating constant resistance.
\n<\/section>\n
\nGraphs (b), (c), and (d) represent non-linear current-voltage characteristics typical of semiconductor devices (like diodes or transistors) or bulk materials under specific conditions (e.g., high electric fields causing velocity saturation). However, for a basic piece of material operating within its ohmic region, the linear relationship is the expected behavior.
