Enhancement of the blue photoluminescence intensity for the porous silicon with HfO(2) filling into microcavities

With HfO(2) filled into the microcavities of the porous single-crystal silicon, the blue photoluminescence was greatly enhanced at room temperature. On one hand, HfO(2) contributes to the light emission with the transitions of the defect levels for oxygen vacancy. On the other hand, the special fill...

description With HfO(2) filled into the microcavities of the porous single-crystal silicon, the blue photoluminescence was greatly enhanced at room temperature. On one hand, HfO(2) contributes to the light emission with the transitions of the defect levels for oxygen vacancy. On the other hand, the special filling-into-microcavities structure of HfO(2) leads to the presence of ferroelectricity, which greatly enhances the blue emission from porous silicon. Since both HfO(2) and Si are highly compatible with Si-based electronic industry, combined the low-cost and convenient process, the HfO(2)-filled porous Si shows a promising application prospect.
