Structure and photoinduced effects in elemental chalcogens: A review on Raman scattering
Spyros N. Yannopoulos
Much progress has been made over a long period, spanning more than a century, in understanding the atomic arrangement on various length scales of noncrystalline chalcogens and thei…
Athermal photoelectronic effects in non-crystalline chalcogenides: Current status and beyond
Spyros N. Yannopoulos
The current critical review aims to be more than a simple summary and reproduction of previously published work. Many comprehensive reviews and collections can be found in the lite…
CO2 Laser-Induced Growth of Epitaxial Graphene on 6H-SiC(0001)
Spyros N. Yannopoulos, Angeliki Siokou, Nektarios K. Nasikas +3
The thermal decomposition of SiC surface provides, perhaps, the most promising method for the epitaxial growth of graphene on a material useful in the electronics platform. Current…
Photoplastic effects in chalcogenide glasses: A review
S. N. Yannopoulos, M. L. Trunov
A synopsis of the various photoinduced changes of rheological, mechanical and elastic properties is presented in the first part of the article. After a critical appraisal of a larg…
Colossal photostructural changes in chalcogenide glasses. Athermal photoinduced polymerization in AsxS100-x bulk glasses revealed by near-bandgap Raman scattering
F. Kyriazis, S. N. Yannopoulos
Near-bandgap Raman scattering was used to induce and study photostructural changes in AsxS100-x bulk glasses revealing a new photoinduced polymerization effect. Raman spectra were…
Understanding the dynamics of biological colloids to elucidate cataract formation towards the development of methodology for its early diagnosis
Spyros N. Yannopoulos, Vassiliki Petta
The eye lens is the most characteristic example of mammalian tissues exhibiting complex colloidal behaviour. In this paper we briefly describe how dynamics in colloidal suspensions…
