Estructura cristalina y propiedades eléctricas de soluciones sólidas YCu_xMn_1-xO₃

Boletín de la Sociedad Española de Cerámica y Vidrio, 2001
Solid solutions belonging to the Mn-rich region of the YCuxMn1-xO3 system have been studied. The powders were prepared by solid-state reaction between the corresponding oxides. Sintered ceramics were obtained by firing at 1100−1200 ºC.

Wafer‐Scale Top‐Down Patterning of Metal Halide Perovskites

Advanced Materials Technologies, EarlyView.
Wafer‐scale patterning of metal halide perovskite films is demonstrated on 150 mm substrates using a chemically amplified resist, polymethyl methacrylate (CAR‐PMMA) and a single reactive ion etching step. The streamlined process preserves film luminescence while defining submicrometer features across the full wafer, enabling dense, scalable integration

Deformation-Induced Mechanical Instabilities at the Core-Mantle Boundary [PDF]

, 2007
Post-Perovskite: The Last Mantle Phase Transition Our understanding of the core-mantle boundary (CMB) region has improved significantly over the past several years due, in part, to the discovery of the post-perovskite phase.

Conductive Tin Oxide Under the Thermal Budget of Perovskite/TOPCon Tandems: Toward Indium‐Free Contacts

Advanced Materials Technologies, EarlyView.
This work demonstrates that achieving conductive undoped SnOx contacts required careful tailoring of oxygen vacancy (VO) tuning and defect engineering. Controlling oxygen deposition pressure and low‐temperature annealing (300°C) optimizes defect stoichiometry and mitigates carrier scattering. This low thermal budget approach significantly enhances Hall

An Examination of the Cs2NaInCl6 Luminescence: Interplay of Self‐Generated In+ and Doped Sb3+, Er3+/Yb3+ Ions

Advanced Optical Materials, EarlyView.
A new luminescence mechanism in Cs2NaInCl₆ is revealed through spontaneously formed In3+→In+ centers and Er3+/Yb3+/Sb3+ doping. Tunable visible, near‐infrared, downconversion, and upconversion emissions are demonstrated, while DFT calculations explain the electronic structure.
