A process for the self-limited layer synthesis (SLS) of WSe₂ on SiO₂ substrates has been developed that provides systematic layer number controllability with micrometer-scale (>90 %) and wafer-scale (~8 cm) uniformity suitable electronic and optoelectronic device applications. This was confirmed by the fabrication and testing of a WSe2 back-gated field effect transistor (FET) using Pd (30 nm) as the contact metal, which exhibited p-type behavior with an on/off ratio of ~106 and a field-effect hole mobility of 2.2 cm2/Vs value, which was higher than has been reported for WSe2-based FETs produced by conventional chemical vapor deposition. On the basis of these results, it is proposed that the SLS method is universally applicable to a range of device applications.

The purpose of this study is to investigate the extent to which primary school teachers of English are aware of critical language assessment with reference to their assessment practice. For these purposes, the teachers’ usual approach of assessment was surveyed, and their thoughts and views on the principles of critical language assessment were analyzed. To conduct the study, a research tool consisting of some open-ended questions and some reading material-based paper work was administered to 19 teachers from 2 different city areas. The results indicate that generally teachers were familiar with the great part of the principles of critical language assessment although the term itself was new to them. Meanwhile there are a number of principles which were not supported by the participants: Obtaining student’s consent and handing over their inherited power to the students. Some areas needing further investigation were identified in the last part of the study.
