Quantum size effects and transport phenomena in thin Bi layers

An analytical solution for quantum size effects on Seebeck coefficient

“…Furthermore, the stronger confinement causes the stronger oscillations in Seebeck coefficient. Similar oscillations due to change of thickness have experimentally been observed in literature for quantum well semimetal and semiconductor structures [11,12]. On the other hand, the oscillations appearing here are due to change of chemical potential and/or carrier density.…”

“…When the characteristic length of the material is comparable to the thermal de Broglie wavelength of the carriers, quantum size effects (QSE) appear and make the transport properties size and shape dependent. In other words, size and shape become new control parameters on transport properties of materials at nanoscale [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16].…”

“…The improvement of thermoelectric materials based on quantum confinement has been first proposed by Hicks and Dresselhaus [4]. After that study, quantum size effects on figure of merit in low dimensional structures became a significant research topic for the development of high performance thermoelectric materials [5][6][7][8][9][10][11][12][13][14]. In literature, mathematical models of quantum size effects are based on numerical calculations of Fermi integrals and they have been developed just for integer dimensions (1D, 2D and 3D) of momentum space.…”

“…Эта ак-туальность обусловлена размерной зависимостью эф-фектов, исследования которых активно ведутся в на-стоящее время на низкоразмерных структурах системы висмут−сурьма: квантовый размерный эффект, переход полуметалл−полупроводник, увеличение термоэлектри-ческой эффективности в тонкой пленке, состояние топо-логического изолятора и др. [1][2][3][4][5][6][7][8][9].…”
