FLEXIBLE CONTROLLABLE ORGANIC PN JOINT FIELD EMISSION ELECTRON SOURCE

摘要

A flexible controllable organic pn joint field emission electron source, consisting of a substrate (001), a lower electrode layer (002), an n-type organic material layer (003), a p-type organic material layer (004) and an upper electrode layer (005), overlapping each other successively. The substrate (001) employs a flexible material substrate, the upper and lower electrode layers (002, 005) employ an organic or inorganic conductive material, the n-type and p-type organic material layers (003, 004) employ an organic material, the p-type organic material layer (004) is an ultrathin material layer and has the advantages of low voltage regulation, low power consumption and a simple preparation process for the field emission electron source, and at the same time it can be prepared as a superlattice organic material layer, which effectively reduces the dispersion of the electron beam, is flexible and convenient to carry, and is suitable in the field of field emission panel displays of controllable cathodes.
