Synthesis and Patterning a New 1-D Semiconductor for Sensors, and Functionalizing the MXene Surface

公开

Quat-Derived Nanostructures (QDNs) are titanium carbide 2-D nanoflakes that are highly oxidized and air-stable. Through their synthesis, I learned that the surface is easily modifiable, making them good for inkjet printing and for further sensor applications. X-Ray Photoelectron Spectroscopy (XPS) enabled me to determine the electronic and structural properties that were changed during synthesis, as the carbon and titanium regions of the spectra reflected the oxidation that occurred. Following synthesis and XPS, I created an ink with the QDNs and completed viscosity and surface tension testing to determine the ability for future inkjet printing capabilities. I also worked on the functionalization of the MXene surface to study the electronic changes that they would produce.
