Researchers from Tsinghua University Detail New Studies and Findings in the Area of Nanotechnology (Scaling-down characteristics of nanoscale diamond-like carbon based resistive switching memories)

By a News Reporter-Staff News Editor at Science Letter -- Investigators publish new report on Nanotechnology. According to news reporting from Beijing, People's Republic of China, by NewsRx journalists, research stated, "A nonvolatile resistive switching random access memory (RRAM) device based on the diamond-like carbon (DLC) films and the inert metal electrodes was demonstrated. A typical unipolar resistive switching (RS) behavior without high voltage 'forming process' is observed."

The news correspondents obtained a quote from the research from Tsinghua University, "It exhibits good scaling-down properties when negligible dependence upon the cell area is observed for V-SET and 'RESET decreases with the reduction of the cell area, which is suitable for practical nonvolatile memory applications. Investigations on the electron transport characteristics at HRS and LRS indicate that Frenkel-Poole emission and Ohmic Laws dominate the LRS and HRS states, respectively."

According to the news reporters, the research concluded: "Based on the conduction mechanism studies, the RS behavior is found to arise from the formation and rupture of conductive sp(2)-like graphitic filaments originating from the connection of conductive sp(2)-like carbon bonds in the predominantly se-like insulating carbon matrix through the electric field induced dielectric breakdown process and thermal fuse effects."
