Abstract
A simple theory of temperature dependence of photoemission is derived with a view to illustrating the main thermal effects. These prove to be: reduction in amplitudes of peaks due to hole state scattering and reduction in the matrix elements, and the shifting of surface state peaks which the authors attribute to narrowing of the band gap within which the surface state exists. Scattering of the escaping electron is relatively unimportant.Keywords
