摘要

研究了不同生长参数对颗粒状铝膜常温电阻率和超导转变温度Tc的影响。具体来说，我们重点研究了在不同衬底温度（从300 K到25 K）下生长过程中氧气流量和铝蒸发速率的影响。我们报告了生长条件，正常状态电阻率和Tc之间的系统相关性。此外，我们的发现为优化颗粒铝的超导特性提供了见解。

期刊介绍： Physica C (Superconductivity and its Applications) publishes peer-reviewed papers on novel developments in the field of superconductivity. Topics include discovery of new superconducting materials and elucidation of their mechanisms, physics of vortex matter, enhancement of critical properties of superconductors, identification of novel properties and processing methods that improve their performance and promote new routes to applications of superconductivity. The main goal of the journal is to publish: 1. Papers that substantially increase the understanding of the fundamental aspects and mechanisms of superconductivity and vortex matter through theoretical and experimental methods. 2. Papers that report on novel physical properties and processing of materials that substantially enhance their critical performance. 3. Papers that promote new or improved routes to applications of superconductivity and/or superconducting materials, and proof-of-concept novel proto-type superconducting devices. The editors of the journal will select papers that are well written and based on thorough research that provide truly novel insights.
