含有p-GaN纳米阵列的InGaN/GaN双异质结太阳能电池的制作

, 2011
提出了一种提高p-GaN/i-InGaN/n-GaN双异质结太阳能电池外量子效率的方法,即将p-GaN刻蚀成纳米阵列结构.我们使用Ni退火形成微结构掩模,通过感应耦合等离子体(ICP)将p-GaN刻蚀纳米阵列结构.同时,提出了两步刻蚀n-GaN台面的制作工艺,以此在形成p-GaN纳米阵列结构时获得光滑的n-GaN层表面,以此改善后续金属电极的沉积.经测试,含有p-GaN纳米阵列结构的电池峰值外量子效率可达55%,比常规p-GaN膜层基InGaN ...

Cholesterol‐Mediated Metabolic‐mechanotransductive Crosstalk Orchestrates Castration Resistance in Prostate Cancer

Advanced Science, EarlyView.
Full androgen deprivation (FAD) induces paracrine cholesterol in prostate cancer that drives the polarization of cancer‐associated fibroblasts (CAFs) and subsequent elevated matrix stiffness. Matrix stiffness in turn potentiates tumor cell survival under FAD pressure via dual mechanotransductive activation of the IRE1α‐XBP1s stress‐response axis ...

具有p-GaN层表面粗化的GaN基LED芯片的制作方法

 一种具有p-GaN层表面粗化的GaN基LED芯片的制作方法,包括：采用金属有机化学气相沉积的方法,在半导体衬底上依次生长低温GaN缓冲层、不掺杂GaN层、N-GaN层、多量子阱层和P-GaN层,形成GaN外延片；将GaN外延片放入蒸发台,在P-GaN层的表面蒸镀CsCl或氯化物；蒸镀结束后,向蒸发台腔室中充入水汽,控制相对湿度使P-GaN层表面的CsCl或氯化物吸收水分逐渐长大形成CsCl或氯化物的纳米岛；将CsCl或氯化物纳米岛作为刻蚀掩膜,对GaN外延片进行刻蚀 ...

Enhanced performance of p-GaN by Mg delta doping

, 2007
The electrical and structural properties of Mg delta-doped GaN epilayers grown by MOCVD were investigated. Compared to uniform Mg-doping GaN layers, it has been shown that the delta-doping (delta-doping) process could suppress the dislocation density and

FOS3D: A Fluorescence‐Enabled Toolkit for Characterizing a Three‐dimensional Osteosarcoma Model

Advanced Science, EarlyView.
FOS3D describes fluorescent (F) osteosarcoma (OS) cells in a tri‐dimensional (3D) model. The study comprises three phases: development, where biofabrication parameters are tuned to achieve cytocompatibility and tumor‐specific mechanical properties in cell‐laden gelatin methacryloyl constructs; validation, where whole‐well fluorescence reading is ...

The Spatiotemporal Genetic Architecture of Seed Vigor in Upland Cotton

Advanced Science, EarlyView.
Leveraging the semi‐automated SeedRanger platform, we profiled the germination kinetics of 356 cotton accessions at a 30‐min interval. This high‐throughput phenomic approach delineated a temporal genetic network comprising 541 stage‐specific loci. Crucially, functional validation identified FLA2 as a pivotal, auxin‐modulated regulator that orchestrates
