Abstract Atomic scale crystallographic structures of a quantum crystals depend on substrate, interfacial strain, defects, surface functionalities etc., which make it challenging to precisely control. To achieve high quality material, UHV conditions are prerequisite, makes costly. Naturally occurring 2D materials have tremendous significance in this regard. White lead, having weak interlayer cou...
A single graphene sheet is stacked on top of monolayer MoS2. The 2D heterostructure buckled out-of-plane, inducing bending in both layers. In article number 2007269, Arend M. van der Zande, Pinshane Y. Huang, and co-workers study the impact interfacial engineering tunability stiffness multilayers. model developed to predict design deformability any arbitrary heterostructure.
We propose a new 2D semiconductor material (TTA-2D) based on the molecular structure of Thiophene-Tetrathia-Annulene (TTA). The TTA-2D structural, electronic, and optical properties were investigated using ab initio methods. Our results show that is small indirect bandgap (0.6 eV). A semiconductor-metal transition can be induced by applying uniaxial strain. also thermally stable up to T = 1000 ...
The accuracy of improved two dimensional finite difference time domain method (2D FDTD) is verified by comparing with 3D FDTD method and experimental data. The optimized 60° photonic crystal waveguide bend, used in this study as a test case, is composed of InPGaAs/InP material and air holes and TE polarization is considered. The photonic crystal waveguide bend transmission data was measured...
The discovery of graphene and its unique properties has inspired researchers to try to invent other two-dimensional (2D) materials. After considerable research effort, a distinct "beyond graphene" domain has been established, comprising the library of non-graphene 2D materials. It is significant that some 2D non-graphene materials possess solid advantages over their predecessor, such as having ...
