Effective mass in bilayer graphene at low carrier densities: The role of potential disorder and electron-electron interaction

Effective mass of electrons and holes in bilayer graphene: Electron-hole asymmetryand electron-electron interaction

Controlling electron-phonon interactions in graphene at ultrahigh carrier densities.

We report on the temperature dependent electron transport in graphene at different carrier densities n. Employing an electrolytic gate, we demonstrate that n can be adjusted up to 4 × 10(14)  cm(-2) for both electrons and holes. The measured sample resistivity ρ increases linearly with temperature T in the high temperature limit, indicating that a quasiclassical phonon distribution is responsib...

Multiband transport in bilayer graphene at high carrier densities

We report a multiband transport study of bilayer graphene at high carrier densities. Employing a poly(ethylene)oxide-CsClO4 solid polymer electrolyte gate we demonstrate the filling of the high-energy subbands in bilayer graphene samples at carrier densities |n| 2.4 × 1013 cm−2. We observe a sudden increase of resistance and the onset of a second family of Shubnikov–de Haas (SdH) oscillations a...

The role of vector potential coupling in hot electron cooling power in bilayer graphene at low temperature

We have studied, in bilayer graphene (BLG), the hot electron cooling power FVP (T, ns) due to acoustic phonons via vector potential (VP) coupling. It is calculated as a function of electron concentration ns and temperature T and compared with FDP (T, ns) that due to deformation potential coupling. For the ns around 1x10 12 cm, FVP (T, ns) is much smaller than FDP (T, ns). With increase of ns, F...

the analysis of the role of the speech acts theory in translating and dubbing hollywood films

از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...
