Furthermore, the temperature under which SMR electrodes annealed is relatively low (60 ☌), making this approach applicable to varies of organic semiconductors, such as spin-coated polymer films, vacuum evaporated films, 2D and even monolayer crystalline films. In addition to that, OFETs with SMR fabricated silver electrodes show lower contact resistance than the ones with evaporated silver electrodes. OFETs based on bilayer crystalline films with solution-processed silver electrodes show comparable performance to devices with transferred gold electrodes. In this work, the silver mirror reaction (SMR) is introduced to construct top-contact electrodes on 2D organic crystalline thin films. Nondestructive method for large scale in-situ electrode deposition is urgent. Up to now, most of the methods reported for fabricating organic field-effect transistors (OFETs) with top-electrodes on the 2D molecular crystals are based on mechanical-transfer method. Organic crystals, especially ultra-thin two-dimensional (2D) ones such as monolayer molecular crystals, are fragile and vulnerable to traditional vacuum deposition. ![]()
