UID/CTM/50025/2013 and EXCL/CTM-NAN/0201/2012 and the European Communities 7th Framework Programme under grant agreement ICT-2013-10-611070 (i-FLEXIS project).In this study, we report solution-processed amorphous zinc tin oxide transistors exhibiting high operational stability under positive gate bias stress, translated by a recoverable threshold voltage shift of about 20% of total applied stress voltage. Under vacuum condition, the threshold voltage shift saturates showing that the gate-bias stress is limited by trap exhaustion or balance between trap filling and emptying mechanism. In ambient atmosphere, the threshold voltage shift no longer saturates, stability is degraded and the recovering process is impeded. We suggest that the trapping time during the stress and detrapping time in recovering are affected by oxygen adsorption/desorption processes. The time constants extracted from stretched exponential fitting curves are ≈106 s and 105 s in vacuum and air, respectively.UNINOVA-Instituto de Desenvolvimento de Novas TecnologiasCENIMAT-i3N - Centro de Investigação de Materiais (Lab.
