Figure 1From: Fine Splitting of Electron States in Silicon Nanocrystal with a Hydrogen-like Shallow DonorCoulomb matrix elements versus dimensionless donor displacement from the dot center. Lower solid line— V ss ; Upper solid line— V pp ; Long-dashed line— V z for h x = h y = 0; Short-dashed line— V zz for h x = h y = 0; Dotted line— V xy for h x = h y , h z = 0Back to article page
