Fine structure of the lowest Landau level in suspended trilayer graphene

Interacting electrons in graphene nanoribbons in the lowest Landau level

Landau level spectrum of ABA- and ABC-stacked trilayer graphene

We study the Landau level spectrum of ABAand ABC-stacked trilayer graphene. We derive analytic lowenergy expressions for the spectrum, the validity of which is confirmed by comparison to a π -band tight-binding calculation of the density of states on the honeycomb lattice. We further study the effect of a perpendicular electric field on the spectrum, where a zero-energy plateau appears for ABC ...

the underlying structure of language proficiency and the proficiency level

هدف از انجام این تخقیق بررسی رابطه احتمالی بین سطح مهارت زبان خارجی (foreign language proficiency) و ساختار مهارت زبان خارجی بود. تعداد 314 زبان آموز مونث و مذکر که عمدتا دانشجویان رشته های زبان انگلیسی در سطوح کارشناسی و کارشناسی ارشد بودند در این تحقیق شرکت کردند. از لحاظ سطح مهارت زبان خارجی شرکت کنندگان بسیار با هم متفاوت بودند، (75 نفر سطح پیشرفته، 113 نفر سطح متوسط، 126 سطح مقدماتی). کلا ...
