(a) Local temperatures probed in the geometrical center of the device as extracted by TCAD simulations (dark cyan solid lines) for \(T_{0}\) equal to 293 and 313 K. We achieve a very good agreement with temperatures calculated after Eq. (4) for \(\alpha = 5.15 \times 10^{5}\) K\(/\)W (pink dashed lines). (b) \(\Delta T_{\mathrm{IMT}}\) (red triangles) and \(\Delta T_\mathrm{MIT}\) (blue triangles) as determined by TCAD simulations for different \(T_{0}\). The dotted lines are the correspondent fits by 2nd order polynomials.
