Abstract
A statistical model of the energy density is used to study the surface properties of an electron-hole drop. The surface energy and dipole layer are calculated. Because the binding energy of an electron is larger than that of a hole, the drop acquires a net negative charge. This charge depends on the excitation conditions and is estimated to be in the range 18-525e for a drop of radius 5 μm.Keywords
