The present chapter deals with the use of infrared spectroscopy in radiation chemistry. After an historical introduction and the presentation of the basic knowledge needed in infrared spectroscopy, we describe the major milestones of its implementation within that field. Section 3 describes the use of infrared spectroscopy in astrophysics. Starting in the 1980s, such studies aim at characterizing the sample s modifications after irradiation. Section 4 describes the implementation of infrared reflection-absorption spectroscopy (IR-RAS) and its use in understanding the radiation-induced surface chemistry. Section 5 is focused on the chemistry induced by swift heavy ions in polymers. Section 6 presents recent developments that enable us to perform... [Pg.201]

LIGHT-EMITTING Si NANOSTRUCTURES IN SiOz LAYERS FORMED BY IRRADIATION WITH SWIFT HEAVY IONS... [Pg.73]

Studies of Si nanostructures are currently an area of intense investigations. Irradiation with swift heavy ions (SHI) may be used for their formation and modification. When SHI penetrate in a target, their stopping occurs just completely at the expense of electronic losses. Therefore, tracks are forming with the nm-scale diameters, where the carrier concentrations may reach 10 cm and temperature exceeds 5000 K for 10 -10 s. [Pg.73]

THERMAL CVD SYNTHESIS OF CARBON NANOTUBES IN SWIFT HEAVY ION TRACKS OF SILICON DIOXIDE... [Pg.471]

During the last years, a growing interest in the creation of micro- and nanoelectronic devices by use of the swift heavy ion track technology in a combination with carbon nanotubes (CNTs) is observed in several research centers worldwide. The CNTs were grown in etched ion tracks in Si02 layers on Si. For this purpose, Ni-catalyst nanoclusters were electrochemically deposited within the ion tracks. The geometry of the obtained nanostructures has been analyzed. Structure features of CNTs obtained by themial chemical vapor deposition have been investigated. [Pg.471]

HUMIDITY AND TEMPERATURE SENSOR PROPERTIES OF p-Si/POLYIMIDE/C6o NANOSTRUCTURES WITH SWIFT HEAVY ION TRACKS... [Pg.628]

Nanostructures based on Cai (fullerite) deposited into swift heavy ion (SHI) tracks in a polyimide layer on a silicon substrate have revealed the pronounced sensitivity to humidity and temperature, which can be associated with the mobility of H and OH ions within the fullaite lattice and electrochemical corrosion in humid environment in the presence of moisture. These sensor effects are larger in the structures with SHI tracks as compared with the structure without the tracks. [Pg.628]

Swift heavy ion beams with extremely high LETs are used to degrade strongly polymer chains within tracks over a range of a few tens of micrometers. After irradiation, the top surface of bulk thermoplastics such as polyethyleneterephtalate, polycarbonate, polyvinylidene fluoride or polyimide materials as well as thin films made of the same material are subsequently etched by a wet chemical treatment that reveals pores of which the shape, surface density and dimensions can be controlled by choosing appropriate conditions. High aspect ratio cylindrical or conical traces of diameter ranging from a few nanometers to some... [Pg.135]
