A solution to the fabrication of amorphous Ga 2 O 3 solar‐blind photodetectors on rigid and flexible substrates at room temperature is reported. robust improvement in response speed achieved by delicately controlling oxygen flux reactive radio frequency magnetron sputtering process. Temporal measurements show that detector quartz has a fast decay time 19.1 µs responsivity 0.19 W −1 as well, which are even better than those single crystal counterparts prepared high temperatures. X‐ray...
Ga2O3, as an emerging optoelectronic material, is very appealing for the detection of ionizing radiation because its low cost, wide band gap (4.5–5.0 eV) and hardness. In this work, a flexible X-ray detector using amorphous Ga2O3 (a-Ga2O3) thin film demonstrated. The a-Ga2O3 was deposited on polyethylene naphthalate (PEN) substrate with delicately control oxygen flux during radio frequency (RF) magnetron sputtering process. Metal/semiconductor/metal-structured photodetectors coplanar...
Abstract Organisms’ life cycles consist of hierarchical stages, from a single phenological stage (for example, flowering within season), to vegetative and reproductive phases, the total lifespan individual. Yet events are typically studied in isolation, limiting our understanding history responses climate change. Here, we reciprocally transfer plant communities along an elevation gradient investigate plastic changes duration sequential for six alpine species. We show that prolonged leads...
Understanding how flowering phenology responds to warming and cooling (i.e., symmetric or asymmetric response) is needed predict the response of future climate change that will happen with occurrence warm cold years superimposed upon a long‐term trend. A three‐year reciprocal translocation experiment was performed along an elevation gradient from 3200 m 3800 in Tibetan Plateau for six alpine plants. Transplanting lower (warming) advanced first date (FFD) transplanting higher (cooling) had...
The timing of the fruit-set stage (i.e., start and end fruit set) is crucial in a plant's life cycle, but its response to temperature change still unclear. We investigated seven phenological events, including dates during 3 yr for six alpine plants transplanted warmer (approximately +3.5°C soils) cooler -3.5°C locations along an altitudinal gradient Tibetan area. found that remained relatively stable under both warming cooling 3-yr transplant experiment. Three earlier events (emergence first...
Abstract Our ability to predict how temperature modifies phenology at the community scale is limited by our lack of understanding responses functional groups flowering plants. These differ among species with different life histories. We performed a reciprocal transplant experiment along four elevation gradients (e.g., 3,200, 3,400, 3,600 and 3,800 m) investigate effects warming (transferred downward) cooling upward) on plant (FFGs) phenological sequences (i.e., seven events). Warming...
Flexible fully transparent diodes with high rectification ratio of 5 × 108 are fabricated all-oxide materials at low temperature. The devices optically in the visible spectra range and electrically robust under mechanically bending. Distinguished from other diodes, these utilize diode-connected thin-film transistor architecture follow field-effect principles.
Desiccation-tolerant cyanobacteria are able to survive frequent cycles of hydration and dehydration, which closely linked diurnal light oscillations. Previous studies have shown that serves as a crucial anticipatory cue, activating desert prepare for desiccation. However, the mechanisms underlying their light-coupled desiccation tolerance remain largely unknown. Here, we demonstrate red-light-induced photosynthetic genes positively regulated by LuxR family transcription factor NfSrr1. We...
Abstract. Grassland soil organic carbon (SOC) is sensitive to anthropogenic activities. Increased disturbance related overgrazing has led widespread alpine grassland degradation on the Tibetan Plateau. The degraded grasslands are considered have great potential for sequestration after adoption of improved management practices. Here, we calibrated and employed Century model investigate effects managements SOC dynamics in meadows. We against plant productivity at Haibei Research Station....
With 2 figures and 5 tables Abstract Low phosphorus (P) stress limits soybean production. A population of 152 recombinant inbred lines (RILs) derived from a cross between ‘Bogao’ (P sensitive variety) ‘Nannong 94‐156’ tolerant 248 markers were used to map quantitative trait loci (QTLs) for low‐P tolerance. Two pot culture trials conducted tolerance evaluated using flower pod abscission rate under low P normal P. Conditional QTLs epistasis also analysed. conditional QTL (near Satt274) on...
Alpine grassland of the Tibetan Plateau is an important component global soil organic carbon (SOC) stocks, but insufficient field observations and large spatial heterogeneity leads to great uncertainty in their estimation. In Three Rivers Source Region (TRSR), alpine grasslands account for more than 75% total area. However, regional (C) stock estimate have seldom been tested. Here we quantified SOC its using 298 profiles surveyed from 35 sites across TRSR during 2006–2008. We showed that...
In the present work, we explore solar-blind ultraviolet (UV) photodetectors (PDs) with enhanced photoresponse, fabricated on Ga/Ga2O3 nanocomposite films. Through pre-burying metal Ga layers and thermally post-annealing laminated Ga2O3/Ga/Ga2O3 structures, films incorporated nanospheres are obtained. For prototype PD, it is found that photocurrent photoresponsivity will first increase then decrease monotonically thickness of pre-buried layer increasing. Each all PDs shows a spectrum response...
In this paper, we report the fabrication of flexible ZnO thin-film transistors (TFTs) on 25-μm-thick copper substrate. The Cu substrate compatible with high-temperature processes was deposited by electroplating, which led to a smooth surface. layer at room temperature, and thermal annealing process conducted 300 °C in air after TFTs. threshold voltage, hysteresis-voltage, contact resistance are improved annealing, whereas mobility, subthreshold swing, ON/OFF ratio barely changed. stabilities...
Direct ZnO x-ray detectors with tunable sensitivity are realized by delicately controlling the oxygen flux during sputtering deposition process. The photocurrents induced x-rays from a 40 kV tube Cu anode increase apparently as decreases, which is attributed to introduction of V o detects. By introducing defects, annihilation rate photo-generated electron-hole pairs will be greatly slowed down, leading remarkable photoconductive gain. This finding informs novel way design based on abundant...
