Evidence of a surface acceptor state in undoped semi-insulating GaAs by photothermal radiometric deep level transient spectroscopy
Siloxane passivated, undoped semi-insulting GaAs samples exhibit a smaller emission time constant in photothermal radiometric signal decay than untreated samples. Surface photovoltage and photoluminescence results for the passivated sample indicate an upwards surface band bending which induces hole...
