This app predicts Tersoff-Hamann approach based scanning tunneling microscopy images of 2D materials in the pre-computed JARVIS-DFT database. There are 716 materials with positive and negative biases with energy range from 0 eV to 0.5 eV and -0.5 eV to 0 eV ranges respectively. Minimum size of xy-size and zcut height from surface can be provided in Angstrom units. zcut is measured from the topmost atom. By default, it is set as 2 Angstrom. ext is used for constant-current setup and refers to applied current in the arbitrary units. If no value is provided, then default values are used.
