Electrons

Build an atom out of protons, neutrons, and electrons, and learn about its mass, charge, structure, and nomenclature. * Describe the structure of an atom * Connect protons to element identity * Connect neutrons to nucleus stability * Connect electrons to ionic charge * Describe the mass and...

Calculation of valence(heavy, light and spin-orbit holes) band and conduction (electrons)band using k*p modelIn case of having troubles in understanding the program, do ask in comments. Platforms: Matlab

A capacitor is a device for storing charge. In this simulation, you can investigate a relatively simple capacitor, known as a parallel-plate capacitor. It consists of two identical metal plates, placed parallel to one another. The capacitor can be charged by connecting one plate to the positive... Platforms: Mac

Are all atoms of a given element the same? How can you tell one isotope from another? Learn about isotopes, and about how to calculate the average atomic mass of an element. Sample Learning Goals: * Define "isotope" using mass number, atomic number, number of protons, neutrons and electrons... Platforms: Mac

GNU Archimedes is the GNU package for the design and simulation of submicron semiconductor devices. It is a 2D Fast Monte Carlo simulator which can take into account all the relevant quantum effects, thank to the implementation of the Bohm effective potential method. The physics and geometry of a... Platforms: *nix, C/C++, BSD

An example call would be >>vibratingString(2).The program is supposed to present an idea on what different vibrational patterns of (closed) strings look like. In string theory, the different vibrational patterns represent different particles, e.g. electrons, neutrons, photons or gravitons.The... Platforms: Matlab

GaAs-GaAlAs Quantum WellIn a type I quantum well, the energy difference d?OCLEg between the larger band gap of the barrier and the smaller band gap of the well material causes a confinement potential both for the electrons in the conduction band and for the holes in the valence band. In a... Platforms: Matlab

The Double Slit Wave-Particle Duality Model demonstrates how matter and light display both wave- and particle-like properties in single and double slit experiments. The simulation shows a detector screen placed behind an aperture with one or two open slits. Particles (electrons or photons) pass... Platforms: Mac
