Current Rectification in a Structure: ReSe(2)/Au Contacts on Both Sides of ReSe(2)

Schottky effect of two-dimensional materials is important for nanoscale electrics. A ReSe(2) flake is transferred to be suspended between an Au sink and an Au nanofilm. This device is initially designed to measure the transport properties of the ReSe(2) flake. However, a rectification behavior is ob...

description Schottky effect of two-dimensional materials is important for nanoscale electrics. A ReSe(2) flake is transferred to be suspended between an Au sink and an Au nanofilm. This device is initially designed to measure the transport properties of the ReSe(2) flake. However, a rectification behavior is observed in the experiment from 273 to 340 K. The rectification coefficient is about 10. The microstructure and elements composition are systematically analyzed. The ReSe(2) flake and the Au film are found to be in contact with the Si substrate from the scanning electron microscope image in slant view of 45°. The ReSe(2)/Si and Si/Au contacts are p-n heterojunction and Schottky contacts. Asymmetry of both contacts results in the rectification behavior. The prediction based on the thermionic emission theory agrees well with experimental data.
