Wide bandgap semiconductors are ideally suited for nonlinear optoelectronics. Because their bandgaps larger than 2 eV, simultaneous absorption of two or more near-infrared photons is necessary to excite the electrons from valence conduction band. Understanding processes that affect multiphoton important in design and fabrication optoelectronic devices. Here, we present an overview photocurrent response photodetectors made GaP, GaN, InGaN, SiC when they excited by at 1.2 eV. Recent...
The legal status of marine fishery resources is analyzed from a spatial perspective: States have the right for their nationals to engage in fishing activities corresponding maritime areas based on sovereignty, sovereign rights, principle freedom high seas as well common heritage mankind Area under 1982 United Nations Convention Law Sea (UNCLOS). Meanwhile, two aspects terms contents: regime exploitation and utilization conservation management resources. transformation natural individual...
Single and multiphoton absorptions in wide band gap semiconductors determine the functionality of photodetectors, lasers, light-emitting diodes (LEDs). Although electronic structure strongly influences different orders semiconductors, it has not been feasible to quantify their contributions on devices. A lack proper measurement techniques hurdle. Here, we present a simple sensitive method based phase modulation femtosecond pulses single-, two-, three-photon GaP InGaN photodetectors. Our...
Wide-bandgap semiconductors are widely used in photonic technologies due to their advantageous features, such as large optical bandgap, low losses, and fast operational speeds. Silicon carbide (SiC) is a prototypical wide bandgap semiconductor with high nonlinearities, electron transport, breakdown threshold. Integration of SiC nonlinear photonics requires systematic analysis the multiphoton contribution device functionality. Here, photocurrent photodetector investigated using...
The question of how to define the legal status marine genetic resources (hereinafter MGRs) in areas beyond national jurisdiction ABNJ) is one important issues negotiation International Legally Binding Instrument under United Nations Convention on Law Sea Conservation and Sustainable Use Marine Biodiversity Areas National Jurisdiction. According theory order justice value law, combining experiences international community handling global ocean problems characteristics MGRs ABNJ, it can be...
A novel "windmill" three-channel light-emitting diode induced fluorescence detector (LED-IF) was proposed to maximize the excitation efficiency and collection efficiency. Compared with typical collinear arrangement, intensity of three channels increased by 7.85, 3.88, 2.94 times, respectively. The compact shaping optical path designed obtain higher a lower background stray light effect caused high divergence angle high-power ultraviolet (UV)-LEDs simultaneously, which sensitivity 4.6 5.7...
