Journal ArticleDOI
Etched ion tracks in silicon oxide and silicon oxynitride as charge injection or extraction channels for novel electronic structures
Dietmar Fink,Alexander Petrov,K. Hoppe,W. R. Fahrner,Ricardo Meurer Papaléo,Alexander S. Berdinsky,Amita Chandra,A. Chemseddine,A. Zrineh,A. Biswas,Franz Faupel,Lewis T. Chadderton +11 more
TL;DR: TEMPOS as mentioned in this paper is a family of tunable electronic material with pores in oxide on silicon structures, which can be used as charge extraction or injection paths towards the conducting channel in the underlying silicon.
Journal ArticleDOI
Modifications in the chemical bonding and optical absorption of PPS by ion bombardment
L.S Farenzena,Ricardo Meurer Papaléo,Anders Hallén,M.A. de Araújo,Rogerio Pohlmann Livi,Bo U. R. Sundqvist +5 more
TL;DR: In this article, a commercial-grade thin poly(p-phenylene sulphide) (PPS) foils, 2 μm thick, have been bombarded with 1H+ (380 keV), and with 0.61 MeV/amu 4He+, 12C2+, 16O3+, 32S3+, 79Br9+ and 127I14+ ions.
Journal ArticleDOI
Radiation damage features on mica and L-valine probed by scanning force microscopy
D.D.N. Barlo Daya,Anders Hallén,J. Eriksson,J. Kopniczky,Ricardo Meurer Papaléo,C.T. Reimann,Per Håkansson,Bo U. R. Sundqvist,Alain Brunelle,Serge Della-Negra,Y. Le Beyec +10 more
TL;DR: In this article, the radiation damage tracks on the surface of muscovite mica due to single 78.2 MeV 127I ions from the Uppsala EN tandem accelerator have been studied using tapping mode scanning force microscopy (TM-SFM).
Journal ArticleDOI
Study of the ion beam induced amorphisation, bond breaking and optical gap change processes in PET
TL;DR: In this article, the effects of ion beam bombardment on the crystalline and chemical structures, as well as in the thermal, optical, and electrical properties of PET (Mylar) were studied.
Journal ArticleDOI
Nanoporous SiO2/Si thin layers produced by ion track etching: Dependence on the ion energy and criterion for etchability
Arícia Oliveira Dallanora,Tatiana Lisbôa Marcondes,Gerardo Bermudez,Paulo Fernando Papaleo Fichtner,Christina Trautmann,Marcel Toulemonde,Ricardo Meurer Papaléo +6 more
TL;DR: In this article, the diameter and the cone angle of the holes were determined as a function of energy loss of the ions, assuming that the etchable track results from the quenching of a zone which contains sufficient energy f...
