Welll...yah, sorta, maybe...<:-))
In its present state it would be extremely expensive to implement 
production wise.  The increase in efficiency or reduction in thermal 
resistance would depend on the number of interfaces  and the materials.  
I doubt they will come near their 10X change in production.  OTOH the 
minimum of 2X should be achievable in production and is a major change.  
If nothing else it would add greatly to the reliability of solid state 
amps.  Now if they could develop them to handle voltage spikes or even 
repetitive spikes<sigh>

We know temperature is molecular movement. The higher the temperature 
the faster the molecules move. Presently we depend on temperature 
between two materials to transfer via mechanical means. This technique 
of bonding by integrating the bonding material into both materials makes 
the transfer much more efficient as the materials act as if they are 
part of each other.  The next step would be to actually have the 
surfaces of the materials actually merge. A thin sheet of gold placed 
between two surfaces will eventually bond to those surfaces as the gold 
molecules will migrate into them, but that may take years, so letting 
nature take care of the process is somewhat impractical.  I imagine 
Palladium will do the same thing. I don't know if any other materials 
have this property or not.
