Nanosized tellurium clusters grown at thiolated β-cyclodextrin molecular template modified electrodes: Electrochemical deposition and STM characterization
Abstract
We report the electrochemical preparation of tellurium nanoclusters at Au(111) electrodes modified with molecular templates. The molecular templates were obtained by properly arranging thiolated β-cyclodextrin (β-CD) self-assembled
monolayers (SAMs) on Au(111) electrodes. Tellurium particles of as small as 1–2 nm in diameter and ∽2
Å in height were observed by in situ electrochemical scanning tunneling
