Abstract

Nanorod arrays of Mercury cadmium telluride (HgCdTe) have potential uses in photovoltaics, infrared detectors, and electro-optical modulators. HgCdTe has semiconductor properties like CdTe, but has the advantage of having a tunable bandgap which is dependent on the amount of Hg incorporated into the structure. Electrodeposition of HgCdTe on lithographically patterned nanoelectrodes, is a low-cost, simple method of producing these nanorod arrays. Nanoelectrodes were defined on indium tin oxide (ITO) coated glass through e-beam lithography, which was then subjected to confined electrodeposition. The nanorod arrays were characterized using powder X-ray diffraction (PXRD), scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy. Photoelectrochemical measurements were performed to determine the photoconductivity of the nanorod arrays.

Biography

Caleb Holtmeyer is a chemistry student pursuing a Bachelor’s of Science at Missouri University of Science and Technology. This is his second year at Missouri S&T and plans to graduate in the spring of 2016. After graduation he hopes to attend graduate school at University of Colorado in Boulder. He has a wide interest in environmental issues and is particularly focused on sustainable energy. By working with Dr. Nath, he has been able to make use of his knowledge in chemistry to develop photoactive nanorods, which have applications in photovoltaics.
