Excitons.
Abstract
From literature searches it can be determined that considerable research is being done in a number of countries, on both theory and experiment relative to excition phenomena. At least one author points this out with the fact that a large number of disciplines are interested in the subject. Two important areas are photosynthesis and animal vision, each being of interest to the photochemist and biologist, respectively. The excition is defined as a quantum of electron excitation energy traveling in a periodic structure whose motion is characterized by a wave vector. This is an idealized definition and a perfect periodic potential is impossible to obtain. Even if the perfect structure could be obtained, surface effects and the atomic vibrations make isolation of the excition effect most difficult. (Author)
