Polarity Assignment in ZnTe, GaAs, ZnO, and GaN-AlN Nanowires from Direct Dumbbell Analysis
Maria de la Mata,César Magén,Jaume Gazquez,Muhammad Iqbal Bakti Utama,Martin Heiss,Sergei Lopatin,Florian Furtmayr,Florian Furtmayr,Carlos J. Fernández-Rojas,Carlos J. Fernández-Rojas,Bo Peng,Joan Ramon Morante,Riccardo Rurali,Martin Eickhoff,Anna Fontcuberta i Morral,Qihua Xiong,Jordi Arbiol,Jordi Arbiol +17 more
TL;DR: The proposed experimental via opens new routes for the fine characterization of nanostructures, e.g., in electronic and optoelectronic fields, where the polarity is crucial for the understanding of their physical properties as well as their growth mechanisms.
Journal ArticleDOI
Tunable Multipolar Surface Plasmons in 2D Ti3C2Tx MXene Flakes
TL;DR: Scanning transmission electron microscopy combined with ultra-high-resolution electron energy loss spectroscopy is used to investigate the spatial and energy distribution of SPs (both optically active and forbidden modes) in mono- and multilayered Ti3C2 T x flakes.
Journal ArticleDOI
MXenes for Plasmonic Photodetection.
Dhinesh Babu Velusamy,Jehad K. El-Demellawi,Ahmed M. El-Zohry,Andrea Giugni,Sergei Lopatin,Mohamed N. Hedhili,Ahmed M. Mansour,Enzo Di Fabrizio,Omar F. Mohammed,Husam N. Alshareef +9 more
TL;DR: The specific ability to detect and excite individual surface plasmon modes provides a viable platform for various MXene-based optoelectronic applications.
Journal ArticleDOI
HCl Flow-Induced Phase Change of α-, β-, and ε-Ga2O3 Films Grown by MOCVD
Haiding Sun,Kuang-Hui Li,C. G. Torres Castanedo,Serdal Okur,Gary S. Tompa,Tom Salagaj,Sergei Lopatin,Alessandro Genovese,Xiaohang Li +8 more
TL;DR: In this paper, a 3-fold increase in the growth rate of pure β-Ga2O3 was achieved by tuning the flow rate of HCl along with other precursors in an MOCVD reactor.
Journal ArticleDOI
