Temperature Characterization of Liquid Crystal Dielectric Image Line Phase Shifter for Millimeter-Wave Applications

open access: yesCrystals, 2021
In this paper we investigate the temperature dependent behavior of a liquid crystal (LC) loaded tunable dielectric image guide (DIG) phase shifter at millimeter-wave frequencies from 80 GHz to 110 GHz for future high data rate communications.

A 21.4 pW Subthreshold Voltage Reference with 0.020 %/V Line Sensitivity Using DIBL Compensation

open access: yesSensors, 2023
This paper presents an ultra-low-power voltage reference designed in 180 nm CMOS technology. To achieve near-zero line sensitivity, a two-transistor (2-T) voltage reference is biased with a current source to cancel the drain-induced barrier-lowering ...

THE TEMPERATURE COEFFICIENT OF PHOTOSYNTHESIS [PDF]

open access: yesJournal of General Physiology, 1919
The temperature coefficient of photosynthesis in Ulva (between 17° and 27°C.) is 1.81. This may be explained by assuming that the process involves a light reaction with a low coefficient followed by an ordinary reaction with a high coefficient.

Tunnel Spin-Polarization of Ferromagnetic Metals and Ferrimagnetic Oxides and Its Effect on Tunnel Magnetoresistance

open access: yesElectronic Materials, 2022
This work presents an examination and unification of fragmented data on spin polarization in half-metallic, ferrimagnetic oxides. It also includes well understood ferromagnetic metals for comparison.

Thin Al1−xGaxAs0.56Sb0.44 diodes with extremely weak temperature dependence of avalanche breakdown [PDF]

open access: yesRoyal Society Open Science, 2017
When using avalanche photodiodes (APDs) in applications, temperature dependence of avalanche breakdown voltage is one of the performance parameters to be considered. Hence, novel materials developed for APDs require dedicated experimental studies.

Mechanisms of increasing predation by planktivorous fish with rising temperature may explain the temperature–body size relationships in zooplankton

open access: yesFrontiers in Ecology and Evolution, 2023
The temperature–size rule (TSR) has been consistently observed in numerous studies, showing that ectotherms reared at higher temperatures experience accelerated growth during the juvenile stage and ultimately reach smaller sizes and younger ages at ...

Enlightening the temperature coefficient of triple mesoscopic CH3NH3PbI3−x Cl x /NiO and double mesoscopic CsFAMAPbI3−x Br x /CuSCN carbon perovskite solar cells

open access: yesJPhys Energy, 2023
Temperature is one of the most crucial outdoor variables that influence the photovoltaic performance and stability of carbon perovskite solar cells (CPSCs), although not many reports are there on temperature-dependent CPSCs performance based on various ...

Investigation of the Temperature Sensitivity of 20-Years Old Field-Aged Photovoltaic Panels Affected by Potential Induced Degradation

open access: yesEnergies, 2022
One effect of moisture ingress on solar panels is potential induced degradation (PID). Solar panels affected by PID experience large leakage currents between the solar cells and the module’s frame, which leads to substantial power degradation.

Temperature Dependence of the Thermo-Optic Coefficient of SiO2 Glass

open access: yesItalian National Conference on Sensors, 2023
This paper presents a thorough analysis on the temperature dependence of the thermo-optic coefficient, dn/dT, of four bulk annealed pure-silica glass samples (type I—natural quartz: Infrasil 301; type II—quartz crystal powder: Heraeus Homosil; type III ...

Stress Effects on Temperature-Dependent In-Plane Raman Modes of Supported Monolayer Graphene Induced by Thermal Annealing

open access: yesNanomaterials, 2021
The coupling strength between two-dimensional (2D) materials and substrate plays a vital role on thermal transport properties of 2D materials. Here we systematically investigate the influence of vacuum thermal annealing on the temperature-dependence of ...
