Impurity Tracking Enables Enhanced Control and Reproducibility of Hybrid Perovskite Vapor Deposition Borchert et al. ACS Appl. Mater. Interfaces, 0:0 (Aug 2019) [ pdf ][ DOI:10.1021/acsami.9b07619 ] Our results indicate that as long as precursor deposition rates are well controlled, physical vapor deposition will allow high solar cell device yields even if the purity of precursors changes from one run to another.	Solution-processed all-perovskite multi-junction solar cells McMeekin et al. Joule, 3:387-401 (Feb 2019) [ pdf ][ DOI:10.1016/j.joule.2019.01.007 ]	Temperature-dependent refractive index of quartz at terahertz frequencies Davies et al. J. Infrared Millim. Terahertz Waves, 39:1236-1248 (Dec 2018) [ pdf ][ DOI:10.1007/s10762-018-0538-7 ]
Raman spectrum of the organic-inorganic halide perovskite ch3nh3pbi3 from first principles and high-resolution low-temperature raman measurements Perez-Osorio et al. J. Phys. Chem. C, 122:21703-21717 (Sep 2018) [ pdf ][ DOI:10.1021/acs.jpcc.8b04669 ]	High electron mobility and insights into temperature-dependent scattering mechanisms in inassb nanowires Boland et al. Nano Lett., 18:3703-3710 (Jun 2018) [ pdf ][ DOI:10.1021/acs.nanolett.8b00842 ] THz and Raman probes reveal very high electron mobility in InAsSb nanowires, and temperature dependent THz measurement reveal charge-carrier scattering mechanisms	Bimolecular recombination in methylammonium lead triiodide perovskite is an inverse absorption process Davies et al. Nat. Commun., 9:293 (Jan 2018) [ pdf ][ DOI:10.1038/s41467-017-02670-2 ] We show that bimolecular charge-carrier recombination in methylammonium lead triiodide perovskite can be fully explained as the inverse process of absorption.
