摘要: The simultaneous measurements of conductance and work function changes induced by gaseous ambient have been performed on α-Fe2O3 thick film polycrystalline samples kept at 280 °C exposed to different atmospheres. switching from n- p-type conductivity is shown an electronic origin, which due the oxygen adsorption formation a surface inversion layer and, therefore, conduction type. modeling n–p described in terms dependence band bending ambient.
