Volume 10
Issue 10

Manganese oxide (MnO2) is a promising material for supercapacitor applications, with a theoretical ultra-high energy density of 308 Wh/kg. However, such ultra-high energy density has not been achieved experimentally in MnO2-based supercapacitors beca

Low voltage resistive memory devices based on graphene oxide–iron oxide hybrid

Autor: Jeong Min Woo, J. R. Rani, Jae-Hyung Jang, Se-I Oh

Publikováno v: Carbon. 94:362-368

Low cost resistive switching memory devices using graphene oxide–iron oxide (GF) hybrid thin films, sandwiched between platinum (Pt) and indium-tin-oxide (ITO) electrodes, were demonstrated. The fabricated devices with Pt/GF/ITO structure exhibited

Self-rectifying bipolar resistive switching memory based on an iron oxide and graphene oxide hybrid

Autor: Se-I Oh, Sung-Min Hong, J. R. Rani, Jae-Hyung Jang

Publikováno v: Nanoscale. 9(40)

A resistive random access memory (RRAM) device with self-rectifying I-V characteristics was fabricated by inserting a silicon nitride (Si3N4) layer between the bottom electrode and solution-processed active material of an iron oxide-graphene oxide (F
