Full-shell Superconductor-Semiconductor Nanowire Heterostructures
Full-shell Naowires 基于全包结构的 superconductor-semiconductor Majorana nanowire 文献整理。 Core-shell Nanowires 2002 年 Lincoln J. Lauhon 等人在 Nature 上发表了Si–Ge core–shell nanowires 和 Si–Ge–Si core–multishell nanowires 等的实验研究文章。 2002_Lauhon_Nature_Epitaxial core–shell and core– multishell nanowire heterostructures.pdf [notice] Latex 引用：[/notice] @article{lauhon2002epitaxial, title={Epitaxial core--shell and core--multishell nanowire heterostructures}, author={Lauhon, Lincoln J and Gudiksen, Mark S and Wang, Deli and Lieber, Charles M}, journal={Nature}, volume={420}, number={6911}, pages={57--61}, year={2002}, publisher={Nature Publishing Group} } Al/InAs Full-shell Nanowires 2015 年 C. M. Marcus 小组 W. Chang 等人在 Nature Nanotechnology 上发表基于 Al/InAs Full-shell 结构的纳米线，并且观察到了显著的 hard gap 。 [notice] Half-shell 和 Full-shell Al/InAs 纳米线隧穿谱对比：[/notice] 2015_Chang_NatureNano_Hard gap in epitaxial semiconductor– superconductor nanowires.pdf [notice] Latex 引用：[/notice] @article{chang2015hard, title={Hard gap in epitaxial semiconductor--superconductor nanowires}, author={Chang, W and Albrecht, SM and Jespersen, TS and Kuemmeth, Ferdinand and Krogstrup, Peter and Nyg{\aa}rd, J and Marcus, Charles M}, journal={Nature nanotechnology}, volume={10}, number={3}, pages={232}, year={2015}, publisher={Nature Publishing Group} } Majorana in Full-shell Nanowires Theory Support 2018 年 Roman M. Lutchyn 等人通过理论计算在 full superconducting shell 与 spin-orbital coupling 共同作用下可以出现Majorana zero modes。目前该文发表在 arxiv 上。 We demonstrate that, in the presence of spin-orbit coupling in the semiconductor induced by a radial electric field, the winding of the superconducting order parameter leads to a topological phase supporting Majorana zero modes. 2018_Lutchyn_arxiv_Topological superconductivity in full shell proximitized nanowires.pdf [notice] Latex 引用：[/notice] @article{lutchyn2018topological, title={Topological superconductivity in full shell proximitized nanowires}, author={Lutchyn, Roman M and Winkler, Georg W and Van Heck, Bernard and Karzig, Torsten and Flensberg, Karsten and Glazman, Leonid I and Nayak, Chetan}, journal={arXiv preprint arXiv:1809.05512}, year={2018} } Experiment 2018 年 C. M. Marcus 小组 S. Vaitiekenas 等人在实验上在 Full-shell 结构中观察到 zero bias peak(ZBP) 信号。目前该文发表在 arxiv 上。 [notice] ZBP[/notice] 2018_Vaitiekenas_arxiv_Flux-induced Majorana modes in full-shell nanowires.pdf [notice] Latex 引用：[/notice] @article{vaitiekenas2018flux, title={Flux-induced Majorana modes in full-shell nanowires}, author={Vaitiek{\.e}nas, Saulius and Deng, M-T and Krogstrup, Peter and Marcus, CM}, journal={arXiv preprint arXiv:1809.05513}, year={2018} } Theory Explanation and Suspicion 2019 年 Penaranda 等人对于 Vaitiekenas 等人的实验文章" Flux-induced Majorana modes in full-shell nanowires" 中的一些问题做出了自己的模型解释。 在此列举两个比较显著的问题： 在较宽的参数范围内出现了 zero bias peak 信号。 偶数倍量子磁通的时候也隐约存在 zero bias peak 信号。 [notice] 参数空间：[/notice] 2019_Fernando_arxiv_Even-odd effect and Majorana states in full-shell nanowires.pdf [notice] Latex 引用：[/notice] @article{penaranda2019even, title={Even-odd effect and Majorana states in full-shell nanowires}, author={Pe{\~n}aranda, Fernando and Aguado, Ram{\'o}n and San-Jose, Pablo and Prada, Elsa}, journal={arXiv preprint arXiv:1911.06805}, year={2019} }
