In-Ga-Zn-O(IGZO) channel based thin-film transistors(TFT), which exhibit high on-off current ratio and relatively high mobility, has been widely researched due to its back end of line(BEOL)-compatible potential for the next generation dynamic random access memory(DRAM) application. In this work, thermal atomic layer deposition(TALD) indium gallium zinc oxide(IGZO) technology was explored. It was found that the atomic composition and the physical properties of the IGZO films can be modulated by changing the sub-cycles number during atomic layer deposition(ALD) process. In addition, thin-film transistors(TFTs) with vertical channel-all-around(CAA) structure were realized to explore the influence of different IGZO films as channel layers on the performance of transistors. Our research demonstrates that TALD is crucial for high density integration technology, and the proposed vertical IGZO CAA-TFT provides a feasible path to break through the technical problems for the continuous scale of electronic equipment.

依循“经济基础决定上层建筑”视角,国家赖以生存和发展的经济基础决定了经济安全保障政策的任务和限度。从任务方面看,在国际经济基础变革背景下,日本强化经济安保政策既有防止“断链”“断产”“断供”的风险规避动因,也有谋求新兴产业国际分工体系制高点的经济竞争动因。但是风险规避的过度安全化和经济竞争的高度政治化造成日益凸显的“泛安全化”趋势。从限度方面看,日本强化经济安保政策效果受现有经济基础制约,包括缺乏足够的劳动力与经济安保政策相匹配,企业间竞争会降低经济安保政策对新兴产业的牵引效果,政企利益分歧会降低日本企业对经济安保政策的配合度和执行力,国际产业竞争将削弱日本构建新兴产业及关键技术联盟的政策效果。

采用气相色谱-质谱-嗅闻仪对新鲜沙棘果汁和沙棘原浆中的气味化合物进行鉴定,分别在新鲜沙棘果汁和沙棘原浆中鉴定出39种和36种气味化合物。进一步发现己酸乙酯、2-甲基丁酸乙酯、3-甲基丁酸乙酯和异戊酸异戊酯具有较高的香气稀释因子,确定是新鲜沙棘果汁中的关键气味化合物。另外,巴氏杀菌之后的沙棘原浆中果香酯类气味化合物的含量显著降低。通过感官评价和电子舌分析发现沙棘原浆的甜度和整体口感优于新鲜沙棘果汁。相比于新鲜沙棘果汁,沙棘原浆中VC和总黄酮的含量明显降低,表明巴氏杀菌会降低沙棘果汁的营养品质。研究成果可以为沙棘产品的风味及营养品质优化提供理论参考。
