                          amount of energy, Q, transferred to or from the solid surface from time t   0 to time t can
                          be found from Figs. 5, 8, and 11.


           1.6  Conduction at the Microscale
                          The mean free path of electrons and the size of the volume involved has long been recognized
                          as having a pronounced effect on electron-transport phenomena. This is particularly true in
























                                                                                         4
