Negative Differential Resistance in Electrochemically Self-Assembled Layered Nanostructures

Electrodeposition of Semiconductors

“…Based on these studies, the authors propose that Cu 2 O is deposited during the positive spikes in electrode potential while a composite of Cu and Cu 2 O is deposited during the more negative plateau region of the oscillation. These Cu/Cu 2 O layered structures also exhibited the phenomenon of negative differential resistance at room temperature [287]. The authors suggest that thin space-charge regions at each Cu/Cu 2 O interface produce double tunnel junctions and that tunneling occurs from the Cu-rich layers into hole states in Cu 2 O through these spacecharge regions.…”

Low-temperature electrodeposition of the high-temperature cubic polymorph of bismuth(III) oxide

“…Commercially available have previously used electrodeposition to create 9-MHz AT-cut quartz crystals (Seiko EG and G superlattices of metal oxides [14][15][16] and nonequilmodel QA-AM9-AU) were used as the working ibrium layered nanostructures of Cu,0 and Cu which electrode during electrochemical quartz crystal mishowed quantum confinement effects in electrical crobalance (EQCM) experiments. The quartz crystals properties [17][18][19][20][21]. Recently, we reported that epihave a coating on both sides consisting of a 500 A Ti taxial films of 8-Bi 2 03 can be electrodeposited on layer beneath a 3000 A layer of Au.…”

Synthesis of Cu/Cu2O core/multi-shelled microcrystal via shape and structure transformation of pre-grown crystals

“…There are some investigations on the syntheses of Cu 2 O powders with varied morphologies [5][6][7][8][9][10][11][12][13] or with hollow structures and complex hierarchy, such as hollow Cu 2 O sphere [14,15], hollow Cu 2 O octahedral [16], hollow Cu 2 O nanocube [17] and hollow Cu 2 O sphere with more one shell [18,19]. The Cu/Cu 2 O layered structure have been prepared by electrodeposition [20,21] and thermal oxidation [22]. However, Cu/Cu 2 O core/multi-shelled truncated octahedron and Cu/Cu 2 O core/multi-shelled octahedron have not yet been reported.…”
