the resistance calculation[edit]

the conductance is given as 12.9k (ohm)-1

how come the resistance is that high in that case..also in nanowire, the electron has high mean free path which implies that the resistance is almost in m ohms

inverse of 12.9k (ohm)-1 is 0.077 m ohms..

please confirm me, if it is correct, or you meant something else.

0.18 micrometer technology[edit]

I have read that chips are now made that use 0.18 micrometer wires.

Have I understood correctly?

That is 180 nanometers, right?

Is this, then, a nanowire?

--> By chips I assume you are referring to VLSI circuits in computer systems. Those are made through a several step etching and deposition method on large silicon substrates. The final product can be considered as filled channels as a better analogy than nanowires. Nano Dan (talk) 19:56, 7 January 2009 (UTC)


I dont know whether that would be called a nanowire (I dont even know who could answer that question =), but I do know that the latest CPUs are built with wires of less than 100nm in width (both Intel and AMD use 90nm for most of their CPUs nowadays I think, and are moving to 65nm), and that should qualify as a nanowire I guess.

In a lab we created 200 nanometer diameter nanowires out of nickel. So I guess 180 nanometers would be a nanowire as well.


Technically, any wire that has a width under 1μm can be called a "nanowire," but the wire would probably only have novel effects if it had a diameter under 40nm or so.

In addition, nanowires of about 10nm in diameter are also observed in bacterial colonies. they can transfer electrons to and from seperate cells.

A simple generator for experiments[edit]

At my (Institute ) we use a very simple setup to show Quantum Conductivity with nanowires.

A simple circuit controls a gold plated relay where the connectors are soft enough to drag thin nanowires between them when the relay switch off. An excellent demonstration if you own a oscilloscope and a signal generator (for controlling the relay). The relay is a RS-12V from Matsushita Automation Controls. I uploaded picture here of the result just in case it could be used in some way.

Expanding the Synthesis Section[edit]

Any objections to expanding the synthesis section with sub-headings and more detailed information or should this go on a separate page? Nano Dan (talk) 20:48, 9 October 2008 (UTC)

Nanowire thickness/width[edit]

Not every structure having a thickness in the tens of nanometers is a nanowire. Every IC has a thin film with a thickness in the tens of nanometers. The width of the structure is the important dimension. I suggest changing the first two lines to:

A nanowire is a nanostructure with a diameter or thickness and width on the order of a nanometer (10−9 meters). Alternatively, nanowires can be defined as structures that have a width and thickness or diameter constrained to tens of nanometers or less and an unconstrained length.

Definition of a nanowire[edit]

I don't see how the definition "the ratio of the length to width being greater than 1000" can be correct, as this would lead to most wires being classified as nanowires. For example a wire of width 3 millimeters need only be 3 meters long to classify. KingSupernova (talk) 04:30, 20 May 2016 (UTC)
