What Are Some Key Features Observed in IV Characteristics?
Several key features can be observed in the IV characteristics of nanoscale devices:
Linear Region: This is where the current increases linearly with the applied voltage, indicative of ohmic behavior. Nonlinear Region: This region demonstrates deviations from Ohm's Law, often due to quantum effects or Schottky barriers. Hysteresis: Some nanoscale devices exhibit hysteresis in their IV characteristics, where the current-voltage path depends on the history of applied voltage, a phenomenon that can be utilized in memory devices. Saturation: At higher voltages, the current may saturate, indicating the limits of charge carrier mobility within the material.
