Enhancement of the lifetime of metastable states in Er-doped Si nanocrystals by external coloured noise
Stefano Spezia, Davide Valenti, Dominique Persano Adorno +1
The changes in the lifetime of a metastable energy level in Er-doped Si nanocrystals in the presence of an external source of colored noise are analyzed for different values of noi…
Enhancement of electron spin lifetime in GaAs crystals: the benefits of dichotomous noise
Stefano Spezia, Dominique Persano Adorno, Nicola Pizzolato +1
The electron spin relaxation process in n-type GaAs crystals driven by a fluctuating electric field is investigated. Two different sources of fluctuations are considered: (i) a sym…
New insights into electron spin dynamics in the presence of correlated noise
Stefano Spezia, Dominique Persano Adorno, Nicola Pizzolato +1
The changes of the spin depolarization length in zinc-blende semiconductors when an external component of correlated noise is added to a static driving electric field are analyzed…
Doping dependence of spin dynamics of drifting electrons in GaAs bulks
Stefano Spezia, Dominique Persano Adorno, Nicola Pizzolato +1
We study the effect of the impurity density on lifetimes and relaxation lengths of electron spins in the presence of a static electric field in a n-type GaAs bulk. The transport of…
Temperature dependence of spin depolarization of drifting electrons in n-type GaAs bulks
Stefano Spezia, Dominique Persano Adorno, Nicola Pizzolato +1
The influence of temperature and transport conditions on the electron spin relaxation in lightly doped n-type GaAs semiconductors is investigated. A Monte Carlo approach is used to…
