Characterization of Mechanical Oscillations in Bismuth Selenide Nanowires at Low Temperatures
Jasulaneca, Liga; Poplausks, Raimonds; Prikulis, Juris; Dzene, Elza; Yager, Tom; Erts, Donats (MDPIO, 2023)A single transistor preamplifier circuit was designed to facilitate electrical detection of mechanical oscillations in nanoelectromechanical systems (NEMSs) at low temperatures. The amplifier was integrated in the close ... -
Graphene Hybrid Metasurfaces for Mid-Infrared Molecular Sensors
Yager, Tom; Chikvaidze, George; Wang, Qin; Fu, Ying (MDPI, 2023)We integrated graphene with asymmetric metal metasurfaces and optimised the geometry dependent photoresponse towards optoelectronic molecular sensor devices. Through careful tuning and characterisation, combining ... -
Time-resolved FDTD and experimental FTIR study of gold micropatch arrays for wavelength-selective mid-infrared optical coupling
Fu, Ying; Yager, Tom; Chikvaidze, George; Iyer, Srinivasan; Wang, Qin (Multidisciplinary Digital Publishing Institute (MDPI), 2021)Infrared radiation reflection and transmission of a single layer of gold micropatch two-dimensional arrays, of patch length ∼1.0 µm and width ∼0.2 µm, have been carefully studied by a finite-difference time-domain (FDTD) ...
