The emission mechanism also enables the photocathode to extract electrons from the positive electron affinity (PEA) surface, and relax the NEA lifetime problem. I-V characteristics of electrons extracted from tip-GaAs shows that the electron beam was \nextracted by field emission mechanism, because a linear dependence was obtained in Fowler-Nordheim \n(F-N) plot. Furthermore, a tip-GaAs cathode has succeeded in generation of spin polarized electron beam. The polarization degree of tip-GaAs is about 34% at excitation photon energy of 1.63eV which is no less than that obtained by an NEA-GaAs cathode.", "subitem_description_type": "Abstract"}]}, "item_10_identifier_60": {"attribute_name": "URI", "attribute_value_mlt": [{"subitem_identifier_type": "DOI", "subitem_identifier_uri": "http://dx.doi.org/10.1063/1.2750952"}, {"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/2237/11993"}]}, "item_10_publisher_32": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "American Institite of Physics"}]}, "item_10_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "Copyright (2007) American Institute of Physics.
