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