In this research, five sizes (100 × 100, 75 75, 50 50, 25 25, 10 µm2) of InGaN red micro-light emitting diode (LED) dies are produced using laser-based direct writing and maskless technology. It is observed that with increasing injection current, the smaller size micro-LED, more obvious blue shift emission wavelength. When current increased from 0.1 to 1 mA, wavelength μm2 micro-LED shifted 617.15 576.87 nm. The attributed stress release high density injection. Moreover, output power very...
The impact of intrinsic amorphous silicon bilayers in silicon/crystalline (a-Si:H/c-Si) heterojunction solar cells is investigated. microstructure factor R* the interfacial a-Si:H layer, which related to Si-H bond and determined by infrared absorption spectroscopy, controlled a wide range varying growth pressure power density plasma-enhanced chemical vapor deposition process. Surface passivation at a-Si:H/c-Si interface significantly improved using an bilayer, i.e., stack layer with large...
The impact of intrinsic amorphous silicon bilayers in silicon/crystalline (a‐Si:H/c‐Si) heterojunction solar cells is investigated. Intrinsic a‐Si:H films with a wide range film densities and hydrogen contents are prepared via plasma‐enhanced chemical vapor deposition (PECVD) technique by modifying various process parameters. For (SHJ) applied as single i‐layers, the resulting surface passivation at a‐Si:H/c‐Si interface poor. However, significantly improved applying bilayers, which composed...
Objectives: In recent years, exploring insights of Patient Reported Outcome (PRO) data has drawn interest in the drug development community. Item Response Theory (IRT) modeling is a mathematical framework commonly used to characterize such composite data. Techniques for PRO exposure response (ER) using IRT models have been developed R/NONMEM [1] and Monolix [2]. Bayesian approaches can offer certain advantages as uncertainty quantification model flexibility, that be useful an modeling. We...
A novel low-profile zeroth-order (ZOR) antenna is presented. The feature of ZOR based on periodic structures employed to reduce the size, while these antennas generally suffer from narrow bandwidth. single-layer asymmetric coplanar waveguide (ACPW) structure proposed realize a bandwidth-extended antenna, where bandwidth characterized by an equivalent circuit model. ACPW not only provides design freedom, but also overcomes constraint traditional CPW. verified both full-wave simulations and...
Lithium–sulfur batteries (LSBs) are promising electrochemical energy storage devices to answer ever-increasing demands. Its practical applications, however, impeded by several technical obstacles, with shuttling of polysulfides as the main cause. A composite approach was developed for design effective sulfur host materials tackle issue. Here, cobalt sulfide nanoparticles embedded in carved N-doped carbon nanoboxes dispersed iron single-atom decorated multiwalled nanotube porous structure,...
Biochemical regulatory networks including genes, proteins and other molecules suffer from internal parametrical fluctuations (thermal, transcriptional, splicing) as well external noises (environmental intercellular). Robustness is an essential property of intracellular biochemical to attenuate the effects fluctuation noise. In this study, several system control schemes are proposed for robust circuit design stochastic linear nonlinear networks. First, stability genetic proteomic discussed...
