Crystalline semiconductor boron quantum dots
WebQuantum Dots Quantum dot solar cells conduct electricity through tiny particles of different semiconductor materials just a few nanometers wide, called quantum dots. Quantum dots provide a new way to process semiconductor materials, but it is difficult to create an electrical connection between them, so they’re currently not very efficient. WebOct 12, 2024 · Boron-doped carbon quantum dots (size 2.3 nm) were fabricated by a modified hydrothermal carbonization one-pot synthesis protocol using 4-hydroxy phenylboronic acid as the common precursor that provided seed for the formation of carbon quantum dots as well as the dopant.
