In copper, for example, the mean free path is 40 nm. Copper nanowires less than 40 nm wide will shorten the mean free path to the wire width. Silver nanowires have very different electrical and thermal conductivity from bulk silver. [34] Nanowires also show other peculiar electrical properties due to their size.
Like silicon, germanium has a high theoretical capacity (1600 mAh g-1), expands during charging, and disintegrates after a small number of cycles. [6] [7] However, germanium is 400 times more effective at intercalating lithium than silicon, making it an attractive anode material. The anodes claimed to retain capacities of 900 mAh/g after 1100 ...
Silicon nanowires, also referred to as SiNWs, are a type of semiconductor nanowire most often formed from a silicon precursor by etching of a solid or through catalyzed growth from a vapor or liquid phase.
A number of approaches are currently being researched, including new forms of nanolithography, as well as the use of nanomaterials such as nanowires or small molecules in place of traditional CMOS components. Field effect transistors have been made using both semiconducting carbon nanotubes [10] and with heterostructured semiconductor nanowires ...
Nanowires based on silicon and manganese can be synthesised from Mn(CO) 5 SiCl 3 forming nanowires based on Mn 19 Si 33. [14] or grown on a silicon surface [15] [16] [17] MnSi 1.73 was investigated as thermoelectric material [18] and as an optoelectronic thin film. [19] Single-crystal MnSi 1.73 can form from a tin-lead melt [20]
Bacterial nanowires (also known as microbial nanowires) are electrically conductive appendages produced by a number of bacteria most notably from the Geobacter and Shewanella genera. [ 1 ] [ 2 ] Conductive nanowires have also been confirmed in the oxygenic cyanobacterium Synechocystis PCC6803 and a thermophilic , methanogenic coculture ...
Nanowire lasers can be grown site-selectively on Si/SOI wafers with conventional MBE techniques, allowing for pristine structural quality without defects. Nanowire lasers using the group-III nitride and ZnO materials systems have been demonstrated to emit in the visible and ultraviolet, however infrared at the 1.3–1.55 μm is important for telecommunication bands.

A degree of photon-number resolution can be achieved in SNSPD arrays, [20] through time-binning [21] or advanced readout schemes. [22] Most SNSPDs are made of sputtered niobium nitride (NbN), which offers a relatively high superconducting critical temperature (≈ 10 K ) which enables SNSPD operation in the temperature range 1 K to 4 K ...
