TiF4 and HfF4 are interesting materials due to their low melting temprature, and they maybe used in electronic devices. But the study about their electronic prpperties is very rare.
Do you know the electronic structure of these materials, including their bandgap structure, the energy positions of conduction and valence band edge, Fermi level, etc.? Thank you!
Zhenrui YuTitanium Tetrafluoride(TiF4)and Hafnium tetrafluoride(HfF4) primarily exhibit ionic bonding due to electron transfer from the metals (Ti/Hf) to fluorine. However, their electronic structure also has some covalent character arising from interactions between metal d-orbitals and fluorine p-orbitals.
Will the Ti and F exist as ionic or molecules in the vapor phase when it heated in vacum?
