Consequently, a local area of the 8/3 approximant in the two-dimensional fullerene quasicrystal consists of single rotational switching fullerenes embedded in a matrix of inert molecules. Furthermore, it is deduced that optimization of the intermolecular interactions between neighboring fullerenes hinders ...
准晶声子熔化This paper is devoted to the study of phonon and melting property of two-demensional Per.rose latrice with five-fold rotational symmetric axis. We intrtoduce a similarity transformation which transforms the dynamical matrix into a block-diagonal matrix, which helps to determine ...
Molecular dynamics simulations together with single-crystal structure analysis emphasize the critical role of the internal rotational and vibrational degrees of freedom of the molecules in the two-dimensional lattice for creating the exclusive SMA phase. This two-dimensional superlattice unifies the ...
The interaction between the translational and rotational degrees of freedom of a diatomic homonu-clear molecule that executes a motion at the site of a two-dimensional close-packed atomic matrix located on a close-packed atomic substrate (a molecular substitutional impurity in the crystal field of ...
35. 2D layers of ZnSe in various structural forms have attracted attention for their photoabsorption properties24,36, as have low-dimensional forms of ZnTe bound to nanowires or in nanoparticle form37,38,39. However, to our knowledge, none of the 2D systems we consider have been studied for...
In this paper, we present a novel scheme to improve the two-dimensional (2-D) direction-of-arrival (DOA) estimation performance for narrowband signals impinging on two orthogonal uniform linear arrays (ULAs). The proposed scheme exploits the cross-correlation matrix information between subarray data...
A one dimensional active vibration absorber with time delayed feedback known as delayed resonator proved to be well applicable for entire vibration absorption of mechanical structure at known excitation frequency. As the main and so far unique result, the delayed resonator concept is transferred from ...
2. Structure, properties and defects of two-dimensional (2D) materials 2.1. Structure and properties of 2D materials Many layered materials have strong in-plane chemical bonds and weak interlayer couplings. These layered structures can be exfoliated into 2D materials with single or only few layers ...
which is valid for spin-rotational invariant low-dimensional systems with exchange interactions. However, both magnetic anisotropy and dipolar interactions are well capable of lifting the Mermin–Wagner restriction. Certainly, there is no lack of attempts to endow two-dimensional (2D) materials with ma...
In this two-dimensional code, data expressed in binary code is divided into cells, and arranged as a two-dimensional matrix-like pattern. The two-dimensional code is characterized b
