Controlling the Performance of a Three-Terminal Molecular Transistor: Conformational versus Conventional Gating
The effect of conformational changes in the gate arm of a three-terminal device is investigated. In the ground state, the gate (triphenyl) arm is nonplanar, where the middle phenyl ring is approximately 30° out-of-plane relative to other two rings. At this geometry, the calculated tunnel current (Id) as a function of external bias (Vds) across the two D−A substituted arms exhibits a typical ins...
متن کاملElectronic conduction in a model three-terminal molecular transistor.
The electronic conduction of a novel, three-terminal molecular architecture, analogous to a heterojunction bipolar transistor, is studied. In this architecture, two diode arms consisting of donor-acceptor molecular wires fuse through a ring, while a gate modulating wire is a pi-conjugated wire. The calculated results show the enhancement or depletion mode of a transistor on applying a gate fiel...

متن کاملCurrent-voltage Characteristics of Molecular Conductors: Two versus Three Terminal
This paper presents a computational study of the feasibility of a molecular transistor. We address the question of whether a “rigid molecule” (one which does not deform in an external field) used as the conducting channel in a standard three-terminal MOSFET configuration can offer any performance advantage relative to a standard silicon MOSFET. Our self-consistent solution of coupled quantum tr...
متن کاملa comparative study of the theme of "marriage" in three victorian novelists: charles dickens, george eliot and thomas hardy
این تحقیق کوشیده است با انتخاب پنج رمان از میان آثار برگزیده، «چارلز دیکنز»، «جورج الیوت» و «توماس هاردی » و با رویکردی تطبیقی به بررسی درونمایه ی «ازدواج» در آثار این سه رمان نویس بزرگ دوره ی ویکتوریا بپردازد. فرضیه ی اولیه ی تحقیق این بوده است که چارلز دیکنز (1870- 1812) با زبانی شوخ و گزنده، جورج الیوت(1880- 1819) با نگاهی آموزشی–اندرزگونه و توماس هاردی(1928- 1840) با رویکردی تلخ وانتقادی به...
