ABSTRACT Introduction Hearing loss and insomnia emerged as preeminent sources of morbidity among military service members veterans who served in the recent Iraq Afghanistan conflicts. Significant threshold shift (STS), an early indicator hearing loss, has not been studied relation to insomnia. This study’s objective was examine co-occurrence STS U.S. personnel with blast-related injury. Materia...

We report the tailoring of the electrical properties of mechanically exfoliated multilayer (ML) molybdenum disulfide (MoS2) by chemical doping. Electrical charge transport and Raman spectroscopy measurements revealed that the p-toluene sulfonic acid (PTSA) imposes n-doping in ML MoS2. The shift of threshold voltage for ML MoS2 transistor was analyzed as a function of reaction time. The threshol...

We used a bilayer field effect transistor (FET) consisting of a thin PbS nanocrystals (NCs) film interfaced with vacuum-deposited pentacene to probe trap states in NCs. We interpret the observed threshold voltage shift in context of charge carrier trapping by PbS NCs and relate the magnitude of the threshold voltage shift to the number of trapped carriers. We explored a series of NC surface lig...
