New pyroelectric phenomena from graded ferroelectric barium strontium titanate thin films
… of graded ferroelectric thin films in uncooled pyroelectric detectors. We built a magnetron sputter system, and developed a method of deposited compositional graded ferroelectric thin films using rf magnetron sputtering, a silicon compatible thin film fabrication process. By obtaining giant …

Room-Temperature Terahertz Detection Based on Graphene and Plasmonic Antenna Arrays
… THz sources and high-responsivity, fast THz detectors. Current commercial products used to detect THz radiation, like Golay cells and pyroelectric detectors, have only slow detection rates and poor sensitivities. Other commercial THz detectors, like bolometers, are more sensitive but require …

Visible and Infrared Light Detection Using 2D Materials
… fast (<1 ms thermal time constant) thermal detectors while still maintaining high specific detectivity. This thesis focuses on developing novel light detectors and harvesters based on 2D materials, including multilayer Tungsten Diselenide (WSe₂) solar cells, ultrathin bolometers, and Bernal …

Plasmonics for On-Chip Photodetectors and Light Sources
<p>Quantum emitters and thermal photodetectors serve as key building blocks for future quantum information and sensing systems. Their properties can be significantly enhanced by integrating them with nanostructured elements, tailoring their interactions with incident optical fields. Quantum …

Preparation and Characterization of Ferroelectric Thin Films for Tunable and Pyroelectric Applications
… studied for their wide applications in pyroelectric detectors and tunable devices. In the present work, pulsed laser deposition (PLD) technique has been employed to deposit ferroelectric Ba(Ti0.85Sn0.15)O3 (BTS) thin films and heterostructures. BTS thin films have been successfully …
