The purpose of this project is to understand the electrical conductivity and infrared absorption spectrum of a hybrid material between Tellurium nanowires and a carbon polymer called PEDOT:PSS. This hybrid material shows much higher conductivity than its components and this behavior gives a great promise for thermoelectric effect. The most intriguing property of this material is observed when taking absorption spectrum from far to near infrared. The hybrid material shows a much bigger absorption edge than Te NW. This project attempts to explain this shift using the confinement energy model and Fermi blocking (due to doping). The result from these two models shows that the absorption can be best explained using the Fermi blocking model in which the hybrid material acts as a highly doped semiconductor. This result might be useful to understand its behavior further by controlling the amount of PEDOT:PSS in the hybrid.
