| Description | This tool computes the current-voltage (I-V) characteristics of quantum dot structures based on the Coulomb Blockade model [1]. The aim is to explore various single charge phenomena that can be noticed via I-V measurements. These include coulomb blockade current plateaus, Negative Differential Resistance (NDR), electronic excitation spectroscopy and spin blockade in double quantum dots. The tool is supported by an additional resource entitled Introduction to Quantum Dot Lab which provides a tutorial to the tool. A tutorial level introduction to the underlying theory can be found in chapters 5 and 6 of “Electron-Phonon and Electron-Electron Interactions in Quantum Transport”, Gerhard Klimeck, Ph.D. thesis, Purdue University, 1994. |
