A unified theory of field‐, thermo‐, and photoemission from metal surface is considered, and the general quantum‐mechanical methods for the investigation of the threshold phenomena are applied. As result the corresponding final expressions are obtained in such a form that it is possible to apply immediately the well known methods of scattering theory for their investigation. Thus, a rigorous foundation for existing formula of emission phenomena is given leading to a more exact form and to restrictions of the frames of their applicability without using any concrete model. Some explanations of the emission phenomena which by traditional theory could not be explained, are suggested. Beside this the new approach to emission phenomena permits further generalization.
