Vor 2 Tagen · Over their 25-plus years, the Reel Alternatives group has donated close to $75,000 to deserving recipients. A few years after they began screening films, one of their primary focuses was improving the Huntsville Library’s collection of DVDs as well as film and media publications. Given the success of these ventures, in 2009, the group ...
Vor 18 Stunden · In this work, calcium fluoride (CaF2) has been employed as an anti-reflection coating (ARC) for gallium arsenide (GaAs) based heterojunction solar cell. A numerical analysis was carried out to optimize performance parameters such as doping concentration, thickness of absorber and window layer, and carrier lifetime. ZnO and GaAs have been employed as window and absorber layer, respectively ...
Vor 5 Tagen · The driver circuit switches two driving TFTs between their two modes to recover the threshold voltage (VTH) shifts during a long sensing period or generate an output waveform with a large pulse width for driving the optical sensor. Experimental results indicate that the degradation of the photocurrent of the photo TFT is suppressed from 3.71 nA to 1.03 nA, representing an improvement of 72.2% ...
Vor einem Tag · Tantalum films incorporated into superconducting circuits have empirically low surface losses, resulting in long-lived qubit states. Remaining loss pathways originate in microscopic defects which manifest as two level systems (TLS) at low temperature. Defects bound qubit performance, recommending careful consideration of tantalum film structures. Here we investigate the growth of tantalum on ...
Vor einem Tag · Single-phase input rectifier brushless DC motor drives with a small film capacitor have many advantages, such as high power density and high reliability. However, when the motor system operates in regenerative braking mode, the dc-link capacitor with reduced capacitance may suffer from overvoltage without adding additional hardware circuits. At the same time, the braking torque control of the ...
Vor einem Tag · As his short film, "A Quiet Monday" continues to make rounds in the film festival circuit, Dika Ofoma announces his next film, "God’s Wife," a - BellaNaija.com. May 13, 2024 News Music
Vor 4 Tagen · Hybrid Circuits. Thin-film substrates are used where conventional PCB technologies cannot provide an adequate technical solution. Rigid and flexible multilayer circuits with highest resolution (10 μm) can be manufactured. Thin-film technology is using semiconductor and microsystem technologies to produce circuit carriers on ceramic ...
