Microwave Process for Improved Optical & Electrical Properties in TCO Semiconductors
Transparent conductive oxide (TCO) layers are an important component of semiconductors within a number of electronic devices including solar cells, touchscreens, and light emitting diodes. Currently, indium tin oxide (ITO) is the most commonly used TCO material due its high electrical conductivity and high optical transparency. However, ITO lacks transparency...

Low Temperature Process to Make Copper Germanide Thin Film (Cu3Ge) Contact and Metallization
Copper Germanide (Cu3Ge) is an exceptional material to use in electronic devices due to its low resistivity. Unfortunately, it is difficult to use Cu3Ge for contacts in solar cells or as interconnections with integrated circuits because its diffusion properties cause degradation of the host material during the application processes. Another issue limiting...

Biosensor and methods of fabricating the same
Copper is an exceptional material to use in electronic devices due to its low resistivity and low cost. One drawback that limits the use of copper in electronics is the high temperatures required to attach the copper to the host material. These temperatures range from 200°C to over 400°C. Most processes require 15 minutes to 3 hours in an oven...
