“…Recently, research attention geared toward chemical and electrochemical synthesis of nanostructured colloidal chalcogenide semiconductors has increased several folds [1][2][3][4][5][6][7][8][9][10]. In this group, Bi 2 Se 3 nano-and microsised clusters, isolated or well-adhered morphological orientations have been reported in literature.…”

“…Nearly spherical grains by chemical bath deposition (CBD) were reported recently by Bari and Patil [2]. Other reports include hexagonal rod like nanostructures by convectional solvothermal method [3] and microplatelets by singlesource precursor metal-organic chemical vapour deposition (MOCVD) [4]. A number of interesting nanostructures such as hexagonal nanosheets and nanotubes through hydrothermal coreduction [5] and hexagonal nanoflakes through a novel solvothermal method [6] were recently fabricated and characterised.…”

Bi 2 Se 3 nanostructures, microsised fibre bundles, and platelets have been synthesised through a simple chemical spray pyrolysis route on glass substrates. Low substrate temperatures (T sub ) favoured growth of nanostructures while elevated T sub was accompanied by increased grain growth and formation of microsised platelets. The nanostructures were identified as nanorods, nanofibers, nanotubes, nanoflowers, and nanoneedles of various aspect ratios. There was an observed red shift of the optical band gap (E opt g ) with increased T sub from 2.40 eV at 95• C to 1.25 eV at 360 • C. Thermo probe measurements confirmed ntype conductivity with dark resistivities which followed a near exponential decline with elevated T sub . The observed changes in optoelectronic properties existing in the different T sub regimes were explained on the basis of microstructural and textural changes in the pristine clusters.

“…Many metal chalcogenide materials can be deposited via CVD techniques and this has stimulated a large amount of work on the development of tailored CVD precursors for their production1314151617. CVD has mostly been used to achieve planar films rather than selective hole filling, and area selective growth is not a natural feature of CVD.…”

Arrays of individual single nanocrystals of Sb2Te3 have been formed using selective chemical vapor deposition (CVD) from a single source precursor. Crystals are self-assembled reproducibly in confined spaces of 100 nm diameter with pitch down to 500 nm. The distribution of crystallite sizes across the arrays is very narrow (standard deviation of 15%) and is affected by both the hole diameter and the array pitch. The preferred growth of the crystals in the <1 1 0> orientation along the diagonal of the square holes strongly indicates that the diffusion of adatoms results in a near thermodynamic equilibrium growth mechanism of the nuclei. A clear relationship between electrical resistivity and selectivity is established across a range of metal selenides and tellurides, showing that conductive materials result in more selective growth and suggesting that electron donation is of critical importance for selective deposition.

The electrochemical reduction of the bismuth ions has been investigated in the tartaric electrolyte. Kinetics and mechanism of the process and the effect of various factors on the electroreduction process of the bismuth ions have been studied according to cyclic and liner polarization curves drawn on the Pt electrodes. According to data, the value of effective activation energy has been calculated. The results of the calculation indicate that the electrochemical reduction process of the bismuth ions is accompanied by electrochemical polarization.
