Polarization dependence of non-linear gain compression factor in semiconductor optical amplifier
(2008)
We investigate the power and the polarization dependence of the intraband dynamics in a bulk semiconductor optical amplifier using both a 2.5-ps pump-probe experimental set-up in contra-propagation and a theoretical model. ...
Plasma formation in a pseudospark discharge
(IEEE, 1989)
Unique features associated with the hollow cathode recess
in a pseudospark discharge have been identified from streak camera
observations. A plasma is observed to form in a highly localized region
immediately behind the ...
MgO-based magnetic tunnel junctions and their applications
(Trinity College (Dublin, Ireland). School of Physics, 2008)
Massive research has been carried out on magnetic tunnel junctions (MTJs), which consist of two ferromagnetic layers sandwiched by a thin insulating barrier, since they were first discovered in 1970. The electrode resistance ...
Origin of hysteresis in resistive switching in magnetite is Joule heating
(2009)
In many transition-metal oxides the electrical resistance is observed to undergo dramatic changes induced by large biases. In magnetite, Fe3O4, below the Verwey temperature, an electric-field-driven transition to a state ...
Perturbative approach to the Kondo effect in magnetic atoms on nonmagnetic substrates
(2011)
Recent experimental advances in scanning tunneling microscopy make the measurement of the conductance
spectra of isolated and magnetically coupled atoms on nonmagnetic substrates possible. Notably, these spectra ...
