Semiconducting polymers inherently exhibit polydispersity in terms of molecular structure and microscopic morphology, which often results a broad distribution energy levels for localized electronic states. Therefore, the bulk charge mobility strongly depends on free density. In this study, we propose method to measure charge-density-dependent conjugated polymer films with widely spread states using conventional field-effect transistor configuration. The gate-induced variation density...

Organizational climate is the ascribed psychological meanings and significance associated with procedures, policies practices that are recognized rewarded in workplace, hence mediates effects of environmental stimuli on individuals’ response. Safety a specific organizational climate, i.e., for safety. Previous research claimed provides foundation safety but without elaboration foundational mechanisms. This paper attempts to fill up this knowledge gap. As multi-dimensional phenomenon, chooses...
