Rice University engineering researcher Isabell Thomann and Rice graduate students Shah Mohammad Bahauddin and Hossein Robatjazi are working with molybdenum disulfide to advance efficiency.
Squeezing light into extremely thin layers and extracting the generated charge carriers is an important problem in the field of two-dimensional materials. Monolayers of 2-D materials have different electronic and catalytic properties from their bulk or multilayer counterparts.
Thomann and her team used a combination of numerical simulations, analytical models and experimental optical characterizations. Using three-dimensional electromagnetic simulations, they found that light absorption was enhanced 5.9 times compared with using MoS2 on a sapphire substrate.
“If light absorption in these materials was perfect, we’d be able to create all sorts of energy-efficient optoelectronic and photocatalytic devices. That’s the problem we’re trying to solve”.
