    • Defects in barrier layers in the multiple quantum-well stack were suspected to be the reservoir in ref. 4. A 10-nm-thick barrier, for example, contains 4 × 1016 cm-2 of Ga-N pairs calculated from the lattice constants, Defects in this amount of material may not be sufficient to be a capacious reservoir of carriers. This is another reason why we believe the acceptor is the reservoir

    • Hole current can be estimated. Conductivity of the p-type layer is approximately 1-6 (Ω cm)-1 at 300K (1018cm -3 × 10cm2 V-1 s-1 × 1.6 × 10-19C, It requires 10V/cm of electric field to carry 16A/cm2. At about 150K, the conductivity becomes 1.6 × 10 -4 (Ω cm)-1 1015 cm-3 and l cm2 V-1 s-1, The electric field required for 16A/cm2 is 105 V/cm. Thus, hole transport approaches a critical condition. See ref. 27 for details
