 ![Annealing of the surface density of oxide charges and the surface-current density at elevated temperatures 00 $^{\circ}$C and 00 $^{\circ}$C. Results are obtained from test fields with crystal orientation &lt;000&gt; produced by CiS. Measurements fit by functions given in eq(0.0) and (0.0) and an exponential function shown.[]{data-label="Figure0"}](Annealing_data_
