About

nextnano++ forms the backbone of the nextnano++ package, a state-of-the-art program that enables solving the Schrödinger, Poisson, and Current equations self-consistently for arbitrary device designs. The algorithms incorporated in nextnano++ have been meticulously crafted to deliver dependable solutions, even for extreme designs under applied bias when used appropriately. As a result, nextnano++ facilitates modeling of systems in equilibrium and quasi-equilibrium states, providing accurate information on current densities, energy profiles, wavefunctions, and electronic band structures while considering the effects of strain, piezo- and pyroelectric charges, and magnetic fields. Additionally, nextnano++ can also compute various optical spectra or electron transport directly based on solutions obtained from the Schrödinger equation.

One of the key advantages of nextnano++ is its exceptional versatility, accommodating a wide range of materials, including group-IV semiconductors and all III-V and II-VI semiconductor binary compounds, as well as their ternaries, quaternaries, and quinternaries. The software supports both zincblende and wurtzite crystal symmetries and arbitrary structure geometries in 1D, 2D, and 3D, defined along any crystallographic direction. Moreover, the syntax of input files used by nextnano++ is continually evolving to keep pace with the increasingly complex demands of modern device design and analysis, while maintaining user-friendliness.
