However, the nature of the defects formed by the irradiation has never been fully clarified. Although defects originating from interstitial carbon (Ci) generated by irradiation are believed to have decreased carrier lifetime, its carrier transition mechanism is still under discussion. Defects induced in n-Si substrates after electron-beam irradiation and subsequent thermal annealing were investigated using Piezoelectric Photo-thermal (PPT) Spectroscopy. PPT technique can defect nonradiative recombination of photo-excited carriers by measuring their generated heat. Deep Level Transient Spectroscopy (DLTS) method was also used to characterize the defect levels. A comparison of the PPT tail-like signal intensity to the defect density and their activation energies obtained from the DLTS suggests that the E3 and E5 defect levels caused the observed PPT tail-like signal. According to the previous DLTS research on Si, the origin of these defects is expected to include Ci. At the same time, the frequency dependence of the PPT signal intensities revealed that the thermal conductivity decreased by irradiation. This fact means that the irradiation treatment introduced crystalline disorder in the sample, as in the case of amorphous Si.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"identifier_registration","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.34481/0002000817","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宮崎大学工学部","subitem_publisher_language":"ja"},{"subitem_publisher":"Faculty
