| [38] | Simulation | 0.3 | 0.4 | 1.5 × 105 | N/A | 95 | 3.3 | 5.2 |
| This work | Simulation | 0.15 | 0.2 | 3.2 × 105 | 15.0% | 120 | 2.1 | 3.8 |
Note: To ensure the rationality of the comparison, this table distinguishes between simulation and experimental results of reference devices. The core comparison focus is on the consistency of performance trends between this work (simulation) and other simulation-based studies [25, 29, 38]. The experimental results [13, 22, 28] are only for reference to reflect the performance gap between simulation and practical application, and do not constitute a direct quantitative comparison basis.
