Abstract Two-dimensional gallium nitride (2D GaN) with a large direct bandgap of ~5.3 eV, a high melting temperature of ~2500 °C, and a large Young’s modulus ~20 GPa developed for miniaturized interactive electronic gadgets can function at high th

Abstract The low-frequency Raman signals of single-wall carbon nanotubes (SWNTs), appearing in the range of 100–300 cm−1, have been interpreted as radial-breathing mode (RBM) comprising pure radial Eigenvectors. Here, we report that most of the l

AAh boron nitride (BN) crystal, assigned to an orthorhombic space group (No. 31, Pm21), is reported here. This new AAh BN crystal exhibits a `linear' morphology for high-resolution transmission electron microscopy (HRTEM) and a (non-hexagonal) `diago

Abstract We elucidate the doping mechanism of suitable elements into borophene with first‐principles density functional theory calculation. During doping with nitrogen (N), the sp2 orbitals are responsible for arranging themselves to accommodate th

For the first time, AA h boron nitride (BN) crystal, assigned to an orthorhombic space group (No. 31, Pm21), is reported. The structure of BN nanotubes is reinterpreted as a helix, resulting from texture and helical growth of the AA h BN crystal used

The structure of h-BN (generally considered to have an AA stacking sequence) has been reinterpreted as AB stacking, based on the classical theory of crystal growth. A growth mechanism is proposed for commercial h-BN platelets as ‘pressure-induced 2

Herein a method is proposed for engineering the electronic properties (including the band structure) of diamond via surface hybridization with graphene. Graphene layers (5–50 nm in thickness) were grown vertically onto a polished 〈110〉 textured

Anisotropic metal nanostructures (e.g., Au–Ag, Au–Cu) are emerging for biomedical and catalytic applications in recent years. Herein, we report a modified synthesis of Cu–Au tripod nanocrystals thr...

Raman spectra of single-wall carbon nanotubes (SWNTs) exhibit a unique radial breathing mode (RBM) band (∼100–300 cm–1) and a G– peak (∼1570 cm–1), along with a D band (∼1350 cm–1). We show that th...
