Electronic & ionic conduction & correlated dielectric relaxations in molecular solids

Zachariah, Manesh (Date of defense: 2016-11-17)

The study of crystalline materials has played a prominent role in solid state physics, whose basic theories were formulated for crystalline matter. However, disordered materials are more abundant in nature than crystalline ...

Neuronal oscillations: from single-unit activity to emergent dynamics and back

Sancristóbal Alonso, Belén de (Date of defense: 2013-07-22)

L’objectiu principal d’aquesta tesi és avançar en la comprensió del processament d’informació en xarxes neuronals en presència d’oscil lacions subumbrals. La majoria de neurones propaguen la seva activitat elèctrica a ...

Nonlinear frequency conversion under general phase mismatched condition: the role of phase locking and random nonlinear domains

Vito, Roppo (Date of defense: 2011-06-15)

In the field of second harmonic (SH) generation most studies have been concerned with maximizing conversion efficiencies, generally achievable at the phase matching (PM) condition. Outside of the PM the conversion efficiency ...

Structural and electrical characterization of doped graphene and carbon nanotube networks

Iqbal, Muhammad Zahir (Date of defense: 2014-07-16)

Graphene, a two-dimensional sp2-hybridized network of carbon atoms has received a remarkable cornucopia of new physics and served as a unique model system, due particularly to its electronic properties, which could have ...

Theoretical and experimental investigation on the visible-light controlled functional properties in charged domain wall ferroelectrics

Ordoñez Pimentel, Jonathan (Date of defense: 2023-03-24)

(English) Optical control of ferroelectric properties has been attracted a growing interest as an alternative to the conventional control by applied electric fields. However, the major drawback for achieving an effective ...
