High emitter profile
Web12 de abr. de 2024 · The parasitic radiation from the hBN white emitter is further compensated by the full-spectrum high reflectivity of the fabricated CCC (measured spectrum shown in Fig. 1C). The hBN white emitter and the CCC form the inner circle of photon recycling, resulting in unidirectional transmission of energy and suppression of … Webphase (omitting the drive-in phase) and a high throughput oxidation by stacking the wafers. We study the achievable charge carrier concentration profiles, the emitter recombination properties, the oxide growth, and the combination with laser doping in comparison to a reference state-of-the-art high temperature process route.
