Development of noble‐metal‐free co‐catalyst is still a research hotspot to promote the photocatalytic H2 evolution performance of graphite phase carbon nitride (CN). In this paper, two dimensional (2D) MoS2 nanosheets were employed as a low‐cost co‐catalyst and loaded onto the porous P doped CN nanosheets (PCNNSs) to fabricate a 2D/2D noble‐metal‐free MoS2/PCNNSs photocatalyst via a simple in‐situ

This paper is dedicated to HfO2‐based ferroelectrics applications in nanoelectronics, especially to topics not well developed up to now, such as microwaves, energy harvesting, and neuromorphic devices working as artificial neurons and synapses. Other well‐covered topics in literature, such as memories or negative capacitance ferroelectric field‐effect transistors, will be only briefly mentioned. The

Dear Reader, In July 2021 physica status solidi (pss) reaches an epic milestone: 60 years of editing, publishing, distributing, and archiving high‐quality materials physics and condensed‐matter research. pss has witnessed six decades of tremendous scientific progress that has changed the way we live. With semiconductor physics laying the foundations for the development of computer electronics and digital

The ozonosphere infiltrates the UV‐A rays (λ=320−400 nm) that reach the Earth’s atmosphere, posing serious health problems such as premature aging and skin cancer. Owing to the importance of UV‐A ray detection, highly detective, novel, and high‐speed UV‐A photodetectors have recently attracted considerable attention. The integration of organic and inorganic hybrid structures yields highly attractive

Sb2Te3 is an end point of quasibinary GeTe‐ Sb2Te3 phase‐change alloys and also a prototypical topological insulator. Topological insulators are materials that behave like insulators in their interior but whose surfaces are characterized by metallic states with linear dispersion, the so‐called Dirac cones. Such surface states are symmetry protected, robust, and are maintained even in the presence of

The Nb3(Al1‐xSnx) superconductor with enhanced critical current density (J c ) is prepared by the process of mechanical alloying (MA) and subsequent low‐temperature sintering. Furthermore, the enhancement mechanism of J c in Nb3(Al1‐xSnx) is discussed emphatically. The analysis on the flux pinning force implies that there is additional pinning mechanism besides grain boundaries pinning in Nb3(Al1‐xSnx)

The effects of Na and RbF alkali treatment on the metastability behavior of CdS/Cu(In,Ga)Se2 solar cells have been investigated with stress factors of heat, junction bias and illumination. Four device types with and without Na or RbF treatments have been subjected to heat‐ and light‐soaking under open‐ and short‐circuit (OC, SC) junction bias. Low‐Na devices show a higher bandgap due to increased minimum
