Charge carrier and phonon transport in nanostructured thermoelectrics
Norouzzadeh, Payam (2012-12)There is currently no quantum mechanical transport model for charge (or phonon) transport in multiphase nano-crystalline structures. Due to absence of periodicity, one cannot apply any of the elegant theorems, such as ... -
Frequency stability in thin-film piezoelectric-on-substrate oscillators
Shahmohammadi Ghahsareh, Mohsen (2013-12)For many years, crystal oscillators have been used as the de facto frequency reference in almost all electronic platforms because they offer excellent stability and superior phase noise. This is mainly due to the high ... -
Performance enhancement of micromachined thin-film piezoelectric-on-silicon lateral-extensional resonators through substrate and tether modifications
Harrington, Brandon Paul (2013-12)Electromechanical resonators have formed the basis of telecommunication circuits for decades through the use of quartz crystal oscillators. Recently, MEMS resonators-based oscillators have become a possible replacement in ...
