Metasurface based uncooled Sixgeyo1-x-y microbolometer for infrared detection
(University of Missouri--Columbia, 2022)
Hz (from 87 Hz) after 4 hours annealing. In addition, the corresponding Hooge's parameters [gamma], [beta] and Kf for the device were 1.02, 2.01, 2.637x10-14, respectively. The measured responsivity and detectivity approached 104 V/W and 108 cm Hz1...
Metasurface integrated uncooled silicon germanium oxide microbolometers for long wavelength infrared detection
(University of Missouri--Columbia, 2022)
]m. The voltage noise power spectral density (PSD) of the fabricated devices were reduced by annealing the devices in vacuum. In addition, the measured TCR, thermal conductance Gth, and absorptivity were 2.5 percent/K, 4.44x10-8 W/K, and 39 percent, respectively...
Impedance and plasmonic based MEMS sensors for chemical and biological applications
(University of Missouri--Columbia, 2020)
that increased the strength of the measured signal by a factor between 4 and 6.25, high sensitivity of 3 cell/ml and detection time of less than 1 hour. The second project is implementing a fiber optic based chemical sensor, which consists of a thin film metal...
