     Define temperature mathematically as it is understood in statistical mechanics.  What is a hole Give an example of a material in which holes play an important role.  Describe what is a Cooper pair. What phenomenon does it give rise to Explain how it does so. 
  
  Solution
The temperature appears fundamentally as a parameter in the Boltzmann factor in statistical mechanics. The temperature is defined based on the system\'s fundamental degrees of freedom.
1/T= d/dE(S(E))
Where E is entropy.
