چکیده

Ge nanostructures were synthesized by reduction of GeO(2) in H(2) atmosphere at various temperatures. Entangled and straight Ge nanowires with oxide shells were grown at high temperatures. Ge nanowires with various numbers of nodules were obtained at low temperatures. Ge nanowires without nodules exhibited remarkable field emission properties with a turn-on field of 4.6 V µm(-1) and field enhancement factor of 1242.

The effect of substrate temperature on fabrication of one-dimensional nanostructures of Tellurium

Tellurium nanostructures have been prepared by physical vapor deposition method in a tube furnace. The experiments were carried out under argon gas flow at a pressure of 1 mbar. Tellurium powder was evaporated by heating at 350°C and 430°C and was condensed on substrates at 110–250°C, in the downstream of argon gas flow. The products were characterized by field emission scanning electron micros...

Non-lithographic formation of three dimensional periodic nanostructures by germanium nanowire etching.

The intrinsic reactivity of curved nanoscale germanium surfaces, under carefully controlled anodic etch conditions, is exploited to produce intricate three-dimensional helical patterns. Such structures, retaining crystalline Ge character and yielding strong visible emission, demonstrate a feature spacing of a periodic nature that correlates with their measured width.

Study of the effect of chemical reduction agent on the synthesis and structural properties of WO3-TeO2 and MoO3-TeO2 two-dimensional compounds.

Preparation of two-dimensional nanostructures of WTe2 and MoTe2 by chemical solution synthesis methods is of great importance. In different synthesis methods, different precursors and concentrations are used. In this paper, we used the chemical reduction reaction method from solution for our analysis. Binary compounds of WO3 - TeO2 and MoO3 - TeO2 were prepared in two processes with reduction a...

Colloidal synthesis of germanium nanocrystals

In this study, colloidal germanium nanocrystals were synthesized by a simple and novel method, and their optical properties were also studied. Polyvinyl alcohol (PVA) as a surface modifier was used to control the optical properties of colloidal Ge nanocrystals. Fourier transform infrared spectroscopy (FTIR) analysis was performed to identify the various functional groups present in the sample. ...
