High hole mobility
The higher Hall mobility compared to the field-effect mobility is due to the removal of the influence from the contact barrier and the surface adsorbates such as H 2 O or O 2 in high vacuum chamber during the Hall measurement. These adsorbates can act as scattering centres to reduce the mobility.
