Towards Direct-Gap Silicon Phases by the Inverse Band Structure Design Approach
H. J. Xiang, Bing Huang, Erjun Kan +2
Diamond silicon (Si) is the leading material in current solar cell market. However, diamond Si is an indirect band gap semiconductor with a large energy difference (2.4 eV) between…
Longitudinal Spin Seebeck Effect Free from the Proximity Nernst Effect
T. Kikkawa, K. Uchida, Y. Shiomi +6
This letter provides evidence for intrinsic longitudinal spin Seebeck effects (LSSEs) that are free from the anomalous Nernst effect (ANE) caused by an extrinsic proximity effect.…
Dynamics of a first order electronic phase transition in manganites
T. Z. Ward, Z. Gai, H. W. Guo +2
By reducing an electronically phase separated manganite (La[1-y]Pr[y])[x]Ca[1-x]MnO3 single crystal thin film to dimensions on the order of the inherent phase domains, it is possib…
Growth diagram of La0.7Sr0.3MnO3 thin films using pulsed laser deposition
Hangwen Guo, Dali Sun, Wenbin Wang +9
An experimental study was conducted on controlling the growth mode of La0.7Sr0.3MnO3 thin films on SrTiO3 substrates using pulsed laser deposition (PLD) by tuning growth temperatur…
Flat Chern Band in a Two-Dimensional Organometallic Framework
Zheng Liu, Zheng-Fei Wang, Jia-Wei Mei +2
By combining exotic band dispersion with nontrivial band topology, an interesting type of band structure, namely the flat chern band (FCB), has recently been proposed to spawn high…
Robust formation of skyrmions and topological Hall effect in epitaxial thin films of MnSi
Yufan Li, N. Kanazawa, X. Z. Yu +6
Magneto-transport properties have been investigated for epitaxial thin films of B20-type MnSi grown on Si(111) substrates. Both Lorentz transmission electron microscopy (TEM) image…
