摘要	Ultrafast photoelectric effects have been observed in MgB2 thin films fabricated by chemical vapor deposition on MgO (1 1 1) substrates. The rise time and full width at half-maximum of the photoresponse pulse signals were about 2.4 and 4 us under the irradiation of a 248 urn laser pulse of 20 ns in duration through the MgO substrate at ambient temperature without any bias. Furthermore, the signal polarity is directly bound up with the laser illumination positions, while no photovoltage was observed when the MgO (1 1 1) single crystal was irradiated. The inner origin mechanism of the present positions-dependent photovoltaic response was discussed. (C) 2011 Elsevier GmbH. All rights reserved.
