Sonochemical Synthesis and Photocurrent of HgTe NANOPARTICLES

We report the sonochemical synthesis of mercury telluride (HgTe) nanoparticles and the photocurrents of these nanoparticles and their organic hybrid system. The HgTe nanoparticles were about 5 nm in size and their lattice structure was cubic. Poly(N-vinylcarbazole)(PVK) was added to the HgTe nanoparticles for the formation of an inorganic(HgTe)-organic(PVK) hybrid system. The room-temperature photocurrents of the HgTe nanoparticles and the HgTe-PVK hybrid system were compared in this study. The photocurrent was significantly enhanced for the HgTe-PVK hybrid system.
