Graphite traces on water surface - A step toward low-cost pencil-on-semiconductor electronics and optoelectronics

We proposed a simple, low-cost and environmentally friendly method for the reproducible fabrication of high quality next-generation pencil-on-semiconductor electronic, optoelectronic and photovoltaic devices by the transfer of dry drawn graphite films on arbitrary planar or nanostructured semiconductor substrates. The proposed transfer technique avoids damage of the surface of semiconductor substrates during the deposition of the drawn graphite films, which is critical for the fabrication of novel electronic and optoelectronic devices.
