Abstract
The current injection into metal/porous Si/bulk Si diodes is investiga ted by transport and photoresponse measurements. Under low forward bia s, the diode current is determined by the space charge region at the p orous Si/bulk Si interface. The activation energy of the photovoltage shows that holes are injected into porous Si states which have little quantum confinement. This is discussed in terms of the confinement mod el for porous Si photoluminescence.
