Patent ID: 8546789

Claim:
A volatile negative differential resistance device, comprising: an upper electrode; a lower electrode; an organic layer disposed between the upper and lower electrodes, the organic layer having a first side adjacent to the upper electrode and an opposite second side adjacent to the lower electrode, wherein the organic layer has a thickness of about 10 nanometers to about 50 nanometers, wherein the organic layer comprises a non-conductive polymer; a barrier layer directly on at least one of the first and second sides of the organic layer; and metal nanoparticles uniformly dispersed in the organic layer, the metal nanoparticles having a diameter of about 10 nm or less, and the metal nanoparticles having an organic material represented by the following formula on a surface of the metal nanoparticles: CH 3 (CH 2 ) n S— wherein n is an integer from 3 to 10 or 12 to 19.
