Nano-Scale Ferroelectric Discovery Paves the Way for Next-Gen Semi-Conductor Technologies

A research team led by Professors Yann-Wen Lan and Ting-Hua Lu from the NTNU Department of Physics has achieved a significant breakthrough in the realm of ferroelectric materials with the development of a ferroelectric crystal based on the two-dimensional material molybdenum disulfide (MoS2) with a thickness of merely 1.3 nanometers.

A Revolutionary Discovery for Solar Cells

In the pursuit of cleaner energy, solar cells are expected to be widely applied in various fields; however, current solar cells are limited in their development due to the low conversion efficiency of light to electricity. To enhance the material's absorption of light, the research team altered the characteristics of light by utilizing twisted light. Photons of twisted light carry an orbital angular momentum. Additional orbital angular momentum is expected to induce more carrier transitions within the material, thereby increasing the material's light absorption and its photogenerated carrier concentration, elevating its potential for application in solar cells. The highlight of this experiment lies in using twisted light to enhance the light absorption of novel 2D material molybdenum disulfide. As the orbital angular momentum of light increments, the concentration of photo-induced carriers rises as well. Consequently, the larger photovoltaic effect in solar cells is enhanced. Based on the results of this experiment, twisted light has shown its potential to become a new approach to enhancing the efficiency of solar cells.
