Punch-Through Drift Tuning

This view frames the fixed-width tradeoff: lock the drift thickness, sweep drift doping, and compare the punch-through and avalanche limits at constant geometry.

At fixed W_fix, higher N_D lowers R_drift,sp, raises V_PT, and lowers the avalanche limit, so the usable blocking point becomes BV_eff = min(BV_PT, BV_AVL).

W_dep(V) = sqrt(2ε_sV/(qN_D)) BV_PT ≈ qN_DW_fix²/(2ε_s) when W_dep = W_fix BV_AVL ≈ ε_sE_C²/(2qN_D) and BV_eff ≈ min(BV_PT, BV_AVL) R_drift,sp ≈ W_fix/(qμ_nN_D) so the knob mainly trades resistance against blocking margin N_D^* ≈ ε_sE_C/(qW_fix) marks the fixed-width crossover between punch-through-limited and avalanche-limited behavior

Drift: Baliga Eq. 1.9, 1.10, 1.11; resistance form Eq. 3.25. Critical field: Baliga Eq. 3.22 for Si and Eq. 3.23 for 4H-SiC. GaN uses the same project scaling form and is labeled as an extension. Loss: MOSFET on-state term follows Baliga Eq. 6.242; switching rows use P_sw = E_swf_sw.
