An Ultrathin Organic Insulator for Metal–Insulator–Metal Diodes [PDF]

open access: yesIEEE Transactions on Electron Devices, 2016
Metal–insulator–metal (MIM) diodes have attracted much attention in recent years because of the possibility of operating at very high frequencies (HFs), well into the terahertz range, a promise first highlighted over 30 years ago. The MIM diode is a quantum device wherein a thin dielectric is sandwiched between two metal electrodes with dissimilar work
