A new study has revealed key factors limiting the efficiency of photoelectrochemical water splitting using a titanium dioxide photoanode for clean hydrogen production. Researchers combined ...

Because boron has one less electron than is required to form the bonds with the surrounding silicon atoms, an electron vacancy or “hole” is created. The n-type silicon is made by including atoms that ...

This ordering enables the confinement of excitons — which are bound electron and hole pairs — to a single layer of CrSBr even inside the 3D material, according to the researchers. UNIVERSITY PARK, Pa.
