Phonon Band Structures and Resonant Scattering in Na<SUB>8</SUB>Si<SUB>46</SUB> and Cs<SUB>8</SUB>Sn<SUB>46</SUB> Clathrates

Rate equations for the phonon peak in resonant-tunneling structures.

The ratio of the phonon peak current to the main peak current in double-barrier resonant-tunneling structures is significantly enhanced by barrier asymmetry. Previously, using the Keldysh formalism, we derived analytical expressions, valid in the zero-temperature, high-bias regime, which explained this eftect. We now provide analytical expressions valid for finite temperature and bias obtained ...

Double-resonant Raman scattering in graphite: Interference effects, selection rules, and phonon dispersion

We present a comprehensive analysis of double-resonant Raman scattering in graphite and derive an analytical expression for the Raman cross section of the D mode in one dimension. The extension to two dimensions does not change the double-resonant phonon wave vectors. In the full integration of the Raman cross section, the contributions by phonons from exactly the K point cancel due to destruct...

manipulation in dubbing and subtitling

پژوهش حاضر در چارچوب مکتب دستکاری قرار گرفت و با استفاده از تقسیم بندی دوکات (2007) از شیوه های دستکاری، به دنبال یافتن پاسخ برای پرسش های زیر بود: 1-رایج ترین شیوه دستکاری در دوبله فیلم ها کدام است؟ 2-رایج ترین شیوه دستکاری در زیرنویس فیلم ها کدام است؟ 3-دستکاری در دوبله فیلم ها رایج تر است یا در زیرنویس آن ها؟ این پژوهش از نوع تحقیقات توصیفی- مقایسه ای و پیکره ای می باشد. پیکره تحقیق شا...
