conductivity of Single Wall Nanotubes (SWNT) is aproximately
"6600 W/m K for an isolated (10, 10) nanotube at room
temperature,"  This is the thermal conductivity along a single
SWNT...So how is 550 W/(cm*cm) an improvement?  RE: Help me

numbers you give are completely different quantities. One is
thermal conductivity in Watts per meter Kelvin, the other is not
really a formal unit, it's just power dissipated per unit area.
It's kind of a useless measurement since it doesn't indicate the
heat delta.  But yeah, if you assume a 1cmx1cm area, and if you
have to move the heat 1cm up from the surface of the chip,
that's [(6600W/mK)*0.01m*0.01m/0.01m], or 66W/k for the number
you quoted. IE, you can move 66W of heat per degree of
temperature difference. Start adding in some interface losses,
and it seems like a pretty good n
