Relationship of STM and AFM images to the local density of states in the valence and conduction bands of rhenium selenide (ReSe2)

Absorption-edge anisotropy inReS2andReSe2layered semiconductors

“…1, the b and a axes are the shortest and second shortest axes in the basal plane; the b axis is parallel to the cluster chains, which corresponds to the longest edge of the plate. 5,11 Measurements were made at several temperatures between 25 and 500 K with a temperature stability of 0.5 K or better.…”

Distribution of the Pb and Sb Atoms in the (Pb, Sb)S Layers of the Franckeite-Type Misfit Compound [(Pb, Sb)S]2.28NbS2 Examined by Scanning Tunneling and Atomic Force Microscopy

“…In the present work we carried out STM and AFM measurements of [(Pb, Sb)S] NbS to examine the distribution of the Pb and Sb atoms in the Q-layer. Atomic-scale STM and AFM images of a layered compound are well described by the partial and total electron density plots [ (r , E $ ) and (r ), respectively] calculated for its layer (13d, 19,20), respectively. For a variety of layered materials, the density plots NbS and showed that the Pb : Sb ratio in the (Pb, Sb)S sheet is close to 3 : 2.…”

Dichroic optical and electrical properties of rhenium dichalcogenides layer compounds

“…The crystal image is in 50× amplification and the crystal orientation of b-axis is indicated. The b-axis is parallel to the metal Re cluster chains, which corresponds to the longest edge of the plate [8,9]. The angular dependency of electrical-resistivity and polarized-absorption measurements for ReX 2 (X = S, Se) was characterized following the rotated indication as shown in Fig.…”
