Phosphorescence by trapping defects in boric acid induced by thermal processing
Luigi Stagi, Luca Malfatti, Alessia Zollo +13
The phosphorescence of boric acid at room temperature is a puzzling phenomenon subject to controversial interpretations although the role of structural defects has not yet been con…
Quantum mechanics at high school: an online laboratory on wave-particle duality
Matteo Tuveri, Daniela Fadda, Carlo Maria Carbonaro
The interest in studying quantum mechanics is always increasing in our society and schools. Especially in the latter case, this leads researchers to implement suitable actions to m…
Cooperative Problem Solving: an experience of high-school teaching updating
Carlo Maria Carbonaro, Alessia Zurru, Viviana Fanti +2
We present the results of an experience of teaching updating dispensed to Italian high-school physics teachers to promote the application of the Cooperative Problem Solving method…
Stability of Ge-related point defects and complexes in Ge-doped SiO_2
C. M. Carbonaro, V. Fiorentini, F. Bernardini
We analyze Ge-related defects in Ge-doped SiO_2 using first-principles density functional techniques. Ge is incorporated at the level of ~ 1 mol % and above. The growth conditions…
Proof of the thermodynamical stability of the E' center in SiO2
Carlo M. Carbonaro, Vincenzo Fiorentini, Fabio Bernardini
The E' center is a paradigmatic radiation-induced defect in SiO2 whose peculiar EPR and hyperfine activity has been known since over 40 years. This center has been traditionally id…
Comment on "Structure and Hyperfine Parameters of E' Centers in alpha-quartz and Vitreous SiO2"
Vincenzo Fiorentini, C. M. Carbonaro
We point out that contrary to a recent suggestion by Boero et al. (PRL 78, 887 (1997)) the +1 charge state of the oxygen vacancy in alpha-quartz cannot be invoked as a candidate E'…
Ab-initio study of oxygen vacancies in alpha-quartz
C. M. Carbonaro, V. Fiorentini, S. Massidda
Extrinsic levels, formation energies, and relaxation geometries are calculated ab initio for oxygen vacancies in alpha-quartz SiO2. The vacancy is found to be thermodynamically sta…
