In recent years, the lead-free double perovskite Cs2AgBiBr6 has emerged as an appealing alternative to lead-based perovskites due its nontoxicity and long-term stability. this study, we employed methyl acetate antisolvent prepared high-quality films by a facile one-step spin-coating method. The exhibited excellent crystallinity with densely packed crystal grains. root mean square roughness average of obtained were 6.69 5.43 nm, respectively. Furthermore, memory device based on uniform...
A soft-start circuit for automobile voltage regulator is presented in this paper. By using a DAC control and frequency detection technology, can provide 17% pre-excitation duty ratio to start the regulator. When alternator achieves cut-in rotational speed, soft increases of driving pulse switching transistor from 100% gradually, which makes magnetizing current increase gradually accordingly suppress burst mechanical torque, avoid engine stalling due an instantaneous overload. Also it has...
The sending and receiving circuit is designed in this paper for ground-based coherent high-frequency radar. system has some functions such as antenna aperture standing wave detection, final-stage power amplifier temperature detection of various source voltages currents; it capable outputting large standing-wave ratio protection time sequence detecting overheating, overvoltage overcurrent, while can also prevent wrong operations, effectively reduce failures increase reliability the whole...
