Abstract

Electronic devices that are made from semiconductors have made a lot of progress in the size of basic components that are more practical and effective, meaning that the size is getting smaller with greater data storage. The progress of these electronic devices cannot be separated from the tunneling effect phenomenon. In the study of quantum physics, a particle with a smaller energy E has a probability of breaking through the potential barrier V. The magnitude of the probability to break through is called transmission coefficient. The purpose of this study was to find the largest transmission coefficient value from the combination of semiconductor materials using the two-dimensional Schrodinger equation. The materials used are III-V alloy semiconductors, that is AlSb, GaP and InAs. Semiconductor materials will be arranged to form a triple potential barrier and will be analyzed numerically using Matlab R2022a. In this study, the maximum energy of an electron is 1 eV. The results showed that the potential barrier structure has an effect on the value of the transmission coefficient. In different combinations of barriers, the two opposite combinations have the same transmission coefficient. The maximum transmission coefficient value is 1000 at the triple potential barrier with ABC and CBA arrangement of 0.3038 eV.
