Ultra-long bismuth telluride nanoribbons synthesis by lithographically patterned galvanic displacement

Synthesis of PbTe and PbTe/Te Nanostructures by Galvanic Displacement of Cobalt Thin Films

“…Therefore, the decrease of the OCP resulting from increasing in the ratio of [Pb 2+ ]/[HTeO 2 + ] in the electrolyte can be attributed to an increase in the deposited Pb content. The trend is consistent with the previously reported work including galvanically deposited Bi x Te y (e.g., thin films, nanowires, and nanotubes) from a sacrificial iron group (i.e., Ni, Co and Fe), where the deposited Bi content increased up to 40% when the ratio of [Bi 3+ ]/[HTeO 2 + ] increased from 0 to 20 mM [18,20,21].…”

“…Fig. 2e and f 20) nanostructures. According to the EDS spectrum, all of the peaks correspond to Pb and Te, indicating that the Co film was completely displaced.…”

“…Galvanic displacement reaction (GDR) is a cost-effective, simple, and versatile approach which can form complex nanostructures with tunable composition and surface morphology. Specifically, GDR is occurred due to the differences in redox potential between sacrificial materials and metal ions in the electrolyte, the composition and surface morphology can be controlled by adjusting experimental conditions including the electrolyte composition and reaction time, as well as altering the sacrificial materials (i.e., material type and thickness) [18][19][20].…”

Programmable synthesis of shape-, structure-, and composition-modulated one-dimensional heterostructures by galvanic displacement reaction

“…[11][12][13][17][18][19][20][21][22][23][24] A few works have been reported for semiconductors. 8,[25][26][27][28] Moreover, GDR is a unique deposition tool that can facilitate the production of nanoparticles, hollow nanoparticles, nanotubes, or monolayer coatings. Recently, heterostructural nanopeapods have even been demonstrated with passive noble metal inclusion; however to date no effort has integrated multiple GDR constructs in a single nanostructure.…”

Electrical/Themoelectric characterization of electrodeposited BixSb2-xTe3 thin films

“…Electrodeposition of A 2 B 3 -type compounds such as Sb 2 Te 3 , Bi 2 Te 3 , and Bi 2 Se 3 have been extensively studied. [4][5][6] However, there is still a lack of information about electroplating of ternary compounds, such as Bi x Sb 2-x Te 3 , Bi x Sb 2-…”
