WebIn the present study, 2D In 2 Se 3 flakes down to monolayers are grown by the chemical vapor deposition (CVD) technique on a mica substrate with their structural, optical and ferroelectric properties being studied. The effect of growth parameters (time of growth and Ar flow rate) on the shape and size of the deposited flakes was studied. WebFeb 9, 2024 · Indium selenide (In 2 Se 3) is an attractive layered semiconductor material with promising optoelectronic and piezoelectric applications. In this work, single-crystalline α -In 2 Se 3 nanobelts are synthesized using a catalyst-free chemical vapor deposition method through the direct selenization of In 2 O 3 powders.

WebAug 1, 2024 · The reversible polarization of ferroelectric semiconductor In 2 Se 3 can be used to realize the tunable photoelectric properties of the heterostructures. In this work, we construct the two-dimensional (2D) Janus WSSe/In 2 Se 3 van der Waals heterostructures (vdWHs), where Janus WSSe monolayer has an intrinsic out-of-plane dipole moment. First … WebThe stable ferroelectricity of 2D α In 2 Se 3 is attributed to its unique re-bonding mechanism and the locking between polarizations in the OOP and IP directions, rather than the long-range Coulomb interactions in conventional displacement-type ferroelectrics. how has diversity helped the army
