Abstract A Bayesian optimization algorithm in combination with a scattering based simulation approach is used for the of quantum cascade detectors (QCDs). QCDs operate mid-infrared and terahertz regime are, together lasers, appropriate integration into on-chip applications such as gas sensors. Our modeling on rate equation model Kirchhoff resistance network noise modeling, using rates calculate...

Pyroelectric properties of orthorhombic Bi2ZnB2O7 (BZBO) crystals were investigated by using the charge integration method. The primary and secondary pyroelectric coefficients BZBO found to be 6.4 −6.5 µC/(m2·°C), respectively. performance was evaluated different figure merits (FOMs), where possessed relatively high current responsivity Fi (10.38 pm/V), detectivity Fd (11.31 × 10−5/Pa1/2). In a...

In this work, a self-powered photodetector device is fabricated through the integration of a palladium-doped molybdenum disulfide thin film on silicon (Pd-MoS2/Si). The substitution of host Mo atoms with Pd dopants in the MoS2 film is revealed by structural and chemical analysis techniques. Due to the incorporation of Pd atoms into the MoS2 films, the photovoltaic characteristics of the fabrica...

Meander line patterned infrared detectors, with values of resistance Ronset at the onset temperature Tc onset of 3–5 kV, were fabricated from YBa2Cu3O72x superconducting material on MgO and SrTiO3 crystalline substrates. Noise voltages from the samples were measured versus bias current, radiation modulation frequency, and temperature, in both the normal and superconducting states. Four major ty...

A complete noise analysis of a two-beam photopyroelectric ~thermal-wave! destructive interferometric sensor instrument is presented and compared to its single-beam, noninterferometric counterpart. The noise analysis is performed using a Green-function formalism applied to experimental observations. The instrumental background noise contribution from the detector and the amplifier is separated f...
