Direct and quasi-direct band gap silicon allotropes with low energy and strong absorption in the visible for photovoltaic applications
Four new sp3-hybridized silicon allotropes (Si10, Si14, Si20-I, and Si20-II) in the space groups of P21/m and P2/m were developed in this study. Their values for properties related to stability, and mechanical, electronic, and optical properties were investigated using the first-principles method. C...
