Relaxed current matching requirements in highly luminescent perovskite tandem solar cells and their fundamental efficiency limits
Alan R. Bowman, Felix Lang, Yu-Hsien Chiang +8
Here we use time-resolved and steady-state optical spectroscopy on state-of-the-art low- and high-bandgap perovskite films for tandems to quantify intrinsic recombination rates and…
Spin-split band hybridization in graphene proximitized with -RuCl nanosheets
Soudabeh Mashhadi, Youngwook Kim, Jeongwoo Kim +8
Proximity effects induced in the 2D Dirac material graphene potentially open access to novel and intriguing physical phenomena. Thus far, the coupling between graphene and ferromag…
Chemical Principles of Topological Semimetals
Leslie Schoop, Florian Pielnhofer, Bettina Lotsch
Initiated by the discovery of topological insulators, topologically non-trivial materials have attracted immense interest in the physics community in the past decade. One of the la…
Similar ultrafast dynamics of several dissimilar Dirac and Weyl semimetals
Chris P. Weber, Bryan S. Berggren, Madison G. Masten +13
Recent years have seen the rapid discovery of solids whose low-energy electrons have a massless, linear dispersion, such as Weyl, line-node, and Dirac semimetals. The remarkable op…
Surface floating 2D bands in layered nonsymmorphic semimetals: ZrSiS and related compounds
Andreas Topp, Raquel Queiroz, Andreas Grüneis +10
In this work, we present a model of the surface states of nonsymmorphic semimetals. These are derived from surface mass terms that lift the high degeneracy imposed in the band stru…
Towards rational design of carbon nitride photocatalysts: Identification of cyanamide "defects" as catalytically relevant sites
Vincent Wing-hei Lau, Igor Moudrakovski, Tiago Botari +6
The heptazine-based polymer melon (also known as graphitic carbon nitride, g-C3N4), is a promising photocatalyst for hydrogen evolution. Nonetheless, attempts to improve its inhere…
