Versatile van der Waals heterostructures of γ-GeSe with h-BN/graphene/MoS₂

Abstract

Recent discovery of a novel hexagonal phase of GeSe (γ-GeSe) has triggered great interests in nanoelectronics applications owing to its electrical conductivity of bulk phase even higher than graphite while...

Centimeter‐Scale PdS2 Ultrathin Films with High Mobility and Broadband Photoresponse

“…As for thermostability for PdS 2 and PdS, the energy and crystalline structure show a small fluctuation, confirming their excellent thermostability at 700 K, which is aligned with the experimental result. [29][30][31] After confirming the relationship between temperature and PdS 2 , we focus on its physical properties research. Angleresolved polarized Raman spectroscopy is used to verify the inherent in-plane anisotropy of PdS 2 films.…”

Abnormal behavior of preferred formation of the cationic vacancies from the interior in a γ-GeSe monolayer with the stereo-chemical antibonding lone-pair state

“…10 Unlike theoretical predictions, the deposited γ-GeSe shows an A–B′ stacked non-centrosymmetric atomic structure. 11 This new structure has aroused great interest with respect to the strain-tunable electronic structure and spontaneous polarization, 12,13 van der Waals heterostructures, 14 and fast Li-ion intercalation properties 15 through first-principles calculations.…”

Strain-induced excellent photocatalytic performance in Z-scheme BlueP/γ-SnS heterostructures for water splitting

“…In stark contrast to the well-studied BlueP-based vdW heterojunctions, the γ-MX monolayers are seldom used to construct vertical heterostructures to the best of our knowledge. 45,46 Among the six γ-MX monolayers, the γ-SnS monolayer has the largest energy gap value and a suitable lattice constant to match with the BlueP monolayer. With the aforementioned considerations in mind, a first-principles study was performed to explore the stabilities, electronic properties, interfacial interactions, and photocatalytic performance of strain-free and strained BlueP/γ-SnS heterostructures.…”
