Solar energy conversion using semiconductors to fabricate photovoltaic devices relies on efficient light absorption, charge separation of electron–hole pair carriers or excitons, and …
We use a first-principles density functional theory approach to calculate the shift current and linear absorption of uniformly illuminated single-layer Ge and Sn monochalcogenides. We …
Ferroelectric (FE) materials, which are non-centrosymmetric crystal systems with switchable polarization characterization, are known to show multifunctional application potential in …
This paper explored physical properties of LiNbO 3 thin films that was deposited on quartz substrate employing spray pyrolysis technique. New raw materials were exploited as the …
Photovoltaic phenomena are widely exploited not only for primary energy generation but also in photocatalytic, photoelectrochemistry, or optoelectronic applications. In contrast to …
The structural, electronic, elastic, mechanical and optical properties of technologically important lithium niobate (LiNbO 3) have been investigated by using the first-principle …
We investigate the shift current bulk photovoltaic response of materials close to a band inversion topological phase transition. We find that the bulk photocurrent reverses direction …
