Understanding the growth mechanism of BaZrS3 chalcogenide perovskite thin films from sulfurized oxide precursors

Anna Fontcuberta i Morral, Elias Zsolt Stutz, Andrea Giunto, Santhanu Panikar Ramanandan, Mirjana Dimitrievska, Iléane Tiphaine Françoise Marie Lefevre

Barium zirconium sulfide (BaZrS3) is an earth-abundant and environmentally friendly chalcogenide perovskite with promising properties for various energy conversion applications. Recently, sulfurization of oxide precursors has been suggested as a viable sol ...

In situ construction of graphdiyne based heterojunctions by a deprotection-free approach for photocatalytic hydrogen generation

Cong Wang, Jian Li

Graphdiyne (GDY) with a direct bandgap, high charge carrier mobility, and ordered pore structure, is considered an excellent matrix for the construction of heterojunction photocatalysts. However, the traditional fabrication methods for GDY-based heterojunc ...

Simultaneous Selective Area Growth of Wurtzite and Zincblende Self-Catalyzed GaAs Nanowires on Silicon

Anna Fontcuberta i Morral, Lucas Güniat, Valerio Piazza, Wonjong Kim, Vladimir Dubrovskii

Selective area epitaxy constitutes a mainstream method to obtain reproducible nanomaterials. As a counterpart, self-assembly allows their growth without costly substrate preparation, with the drawback of uncontrolled positioning. We propose a mixed approac ...

Cd-113 Solid-State NMR at 21.1 T Reveals the Local Structure and Passivation Mechanism of Cadmium in Hybrid and All-Inorganic Halide Perovskites

David Lyndon Emsley, Dominik Józef Kubicki, Daniel Prochowicz, Albert Hofstetter, Brennan James Walder

Cadmium doping has recently emerged as an efficacious strategy for defect suppression and band gap tuning in hybrid as well as all-inorganic halide perovskites. However, the cadmium speciation in these materials is unknown. Here, we use high-field cadmium- ...

Measuring the Optical Absorption of Single Nanowires

Anna Fontcuberta i Morral, Wonjong Kim, Simon Robert Escobar Steinvall

In this work we present a method to quantitatively measure the optical absorption of single nanowires that can be applied over a wide range of temperatures and with a high enough sensitivity to enable the measurement of below-band-gap absorption (as well a ...

Tuning adatom mobility and nanoscale segregation by twin formation and polytypism

Anna Fontcuberta i Morral, Federico Matteini, Gözde Tütüncüoglu, Luca Francaviglia

Nanoscale variations in the composition of an AlxGa1−xAs shell around a GaAs nanowire affect the nanowire functionality and can lead to the formation of localized quantum emitters. These composition fluctuations can be the consequence of variations of crys ...

Zinc blende-wurtzite polytypism in nanocrystalline ZnO films

Christophe Ballif, Cécile Hébert, Aïcha Hessler-Wyser, Duncan Thomas Lindsay Alexander, Sylvain Nicolay, Lorenzo Fanni, Arthur Brian Aebersold

ZnO is commonly observed and assumed to crystallize fully in a wurtzite structure. Indeed, While polytypism between a wurtzite and a zinc blende phase is often seen in some II-VI compounds, it has only rarely been observed in ZnO. Here, by means of automat ...

Metathesis of a U(V) imido complex: a route to a terminal U(V) sulfide

Rosario Scopelliti, Marinella Mazzanti, Marta Falcone, Rory Patrick Kelly

Herein, we report the synthesis and characterisation of the first terminal uranium(V) sulfide and a related UV trithiocarbonate complex supported by sterically demanding tris(tert-butoxy)siloxide ligands. The reaction of the potassium-bound UV imido comple ...
