# Talk:Nanowire

It is vital that you Podcast your pages, or/and allow the information to be downloaded via MP3 so that it can be acknowledged and digested at leisure through a computer or other Audio systems:

## the resistance calculation

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

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

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

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

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.
