Abstract
The FDTD method is being used to calculate transmission in nanoscale transistors using the Python programming language. The programs being used are three-dimensional implementations of the time-dependent Schrodinger Equation. Transmission is calculated by initializing a waveform representing an electron at the input of a transistor potential and using the FDTD method to simulate the interaction of the particle as it passes through the channel of the transistor. The percentage of the particle that passes through is the transmission. Simulations are done for MOSFET and FinFET transistors. The transmission is then used to calculate the current in the transistor for various bias voltages.
