Proposal for a THz Spectroscopic Sensor Based on Semiconductor Quantum Cascade Lasers
SUMMARY There are a number of different types of laser based chemical sensors that can sense the absorption or refractive index of an analyte at a single or range of frequencies. Absorption spectroscopy is most common for gas sensing. Chemicals in condensed and liquid phases are sensed using evanescent-wave techniques that provide sensitive detecti...

Engineered Crystallization of Atomic Layer Deposited Amorphous Metal Oxides
SUMMARYLehigh University has developed low-cost but high quality crystalline substrates and coatings of metal oxides. These substrates could be a replacement for other, more expensive coatings and substrates such as single crystal sapphire (aluminum oxide). Anytime an inorganic semiconductor is used it must be grown on a high crystalline quality s...
