Method and device to modify the electrical properties of an organic and/or molecular material

摘要

The present invention concerns a method to modify the electrical conductivity of an organic and/or molecular material comprising the steps of providing a reflective or photonic structure and of placing said organic and/or molecular material in or on said structure. Method characterized in that it consists further in providing a structure (1) which has an electromagnetic mode which is by design, or can be made by way of adjustment or tuning, resonant with a transition in said organic and/or molecular material (2) and in controlling, in particular enhancing, the mobility of the charge carriers, and thus the electrical current, in said organic and/or molecular material (2), by means of strongly coupling said material (2) to the local electromagnetic vacuum field and exploiting the formation of extended macroscopic states in said material.
