• 15:10, 29 January 2024 Tal talk contribs created page Construction:Plot exciton wavefunction (Created page with "The exciton wavefunction can be written as <math>\psi_\lambda\left(r_e,r_h\right)=\sum_{vc} A_{vc}^\lambda \psi_v(r_h)\psi_c^*(r_e)</math> and depends on coordinates of a hole as well as an electron, thus two coordinates. In order to represent this function in 3D space we need to fix either the position of the electron $\psi_\lambda(r^*_e,r_h)$ or that of the hole $\psi_\lambda(r_e,r^*_h)$ File:HBN exciton.png|500px|thumb|Charge density of the first bright exciton...")
