Resistive Switching in CsPbBr3 (0D)/MoS2 (2D) Heterojunction System: Trap-Controlled Space Charge Limited Transport Mechanism

“…Indeed, following the discovery of graphene, immense interest has grown in the synthesis, properties and applications of a wide range of 2D materials including conductors, semiconductors, insulators. Dichalcogenides, in general, and MoS 2 , in particular, have attracted immense interest due to their excellent electrical, optical and mechanical properties. − Correspondingly, various applications of MoS 2 in the fields of catalysis, electronics devices, and energy have been demonstrated. − Recently, a MoS 2 layered structure has also been integrated as a functional material in memristors. − In these studies, generally, MoS 2 is synthesized by physical methods such as CVD, mechanical exfoliation, etc. Halide perovskite materials have also emerged rapidly during the past several years as interesting and highly promising optoelectronic materials for solar cell and LED applications, a hallmark of the significant interest being their property tuneability. , Recently it was discovered that coatings of these materials also exhibit RS behavior.…”

To the Stability of Janus Phases in Layered Trichalcogenide MPX3 Crystals: Insights from Experiments and Theory

“…Two-dimensional (2D) materials have attracted tremendous research interest since the breakthrough of graphene. − Their atomic thickness and huge specific surface area make them easy to design and manipulate. The unique optical, electronic, and mechanical properties of these materials offer great potential for their use as key components in new electronic and optoelectronic applications. − During the past two decades, a plethora of 2D materials have been developed and rediscovered. , Here, the chalcogenide-based 2D materials can be allocated to a separate group, which contains transition metal dichalcogenides (such as MoS 2 , WS 2 , and WSe 2 ), consisting of a sandwiched structure of a transition metal layer between two chalcogen layers (Figure a,b), group-III-element 2D chalcogenides, such as GaSe 2 , which come in different polytypes per their layer stacking configuration, and the group-IV-element 2D chalcogenides consisting of the buckled and puckered monochalcogenides (e.g., SnS and GeSe) . These materials on their turn can serve as the building blocks for the development of more complicated examples, like MPX 3 , (M: transition metal and X: chalcogen, S or Se), whose structure can be seen as layered MX 2 crystals with one-third of the M sites being substituted with P–P pairs (Figure c,d).…”

Optimizing density-functional simulations for two-dimensional metals

“…The discovery of graphene nearly two decades ago sparked an entire new research field of two-dimensional (2D) materials [1]. The 2D materials pedigree has expanded ever since, thanks to unique properties and visions for novel applications [2][3][4][5]. Most 2D materials are covalently bound and have layered structures easily exfoliable from three-dimensional (3D) bulk matter [6,7].…”
