چکیده

The electronic and photoconductive characteristics of CdTe nanowire-based field effect transistors were studied systematically. The electrical characterization of a single CdTe nanowire FET verifies p-type behavior. The CdTe NW FETs respond to visible-near infrared (400-800 nm) incident light with a fast, reversible and stable response characterized by a high responsivity (81 A W(-1)), photoconductive gain (∼2.5 × 10(4)%) and reasonable response and decay times (0.7 s and 1 s, respectively). These results substantiate the potential of CdTe nanowire-based photodetectors in optoelectronic applications.

Bi-Assisted CdTe/CdS Hierarchical Nanostructure Growth for Photoconductive Applications

We developed a method to control the structure of CdTe nanowires by adopting Bi-mixed CdTe powder source to a catalyst-assisted chemical vapor deposition, which allowed us to fabricate CdTe/CdS hierarchical nanostructures. We demonstrated that diverse nanostructures can be grown depending on the combination of the Bi powder and film catalysts. As a proof of concepts, we grew CdTe/CdS branched n...

Electrical properties of ZnO nanowire field effect transistors by surface passivation

We have synthesized single crystalline ZnO nanowires by thermal evaporation method and fabricated individual ZnO nanowire field effect transistors (FETs) to investigate their electrical properties. ZnO nanowires are strongly affected by O2 molecules in ambient. For example, surface defects such as oxygen vacancies act as adsorption sites of O2 molecules, and the chemisorption of O2 molecules de...
