3.3.3 The Insulator-Metal Interface

The condition for the potential at the insulator-metal interface reads:

    $\displaystyle \varphi_s = \varphi_m - \varphi_{W}  $where$\displaystyle    \varphi_{W} = -\frac{E_W}{q}$ (3.97)

with $ E_W$ the work function energy of the metal at the insulator surface. The thermal condition reads:
    $\displaystyle T_{L} = {\it T}_\mathrm{C}$ (3.98)

i.e., the lattice temperature $ {\it T}_\mathrm{L}$ in the insulator at the boundary is continuous and determined by the contact temperature $ {\it T}_\mathrm{C}$.
