Effect of cross capacitance in three-junction single-electron transistors

Sensing mechanism of metal‐decorated single‐walled carbon nanotube field effect transistor sensors

“…2b, clearly periodic oscillations with a 10 mV period are superimposed on the Coulomb oscillation peaks. Such beat patterns were previously observed from multi‐dot SETs 14, and are known to derive from a cross‐capacitance between neighboring islands. As shown in the AFM images in Figs.…”

Aging, rejuvenation and memory due to domain-wall contributions in RbH 2 PO 4 single crystals

“…RbH 2 PO 4 (RDP) belongs to KDP-type single crystals, which show high dielectric domainwall contributions within the plateau range T c > T > T f [32][33][34][35]. The domain-wall response gradually freezes in [36] upon cooling below T f ≈ 118 K. A 180 • domain structure forms at T c = 146 K, with planar ferroelectric/ferroelastic walls aligned with either of the two equivalent tetragonal a-axis.…”

Non-Debye domain wall response in KH 2 PO 4

“…The physical nature of the anomalously high permittivity observed in potassium dihydrogen phosphate (KH 2 PO 4 ) within the so-called plateau range below the paraelectricferroelectric phase transition temperature T c = 123 K had attracted considerable interest for many decades [1][2][3][4][5][6][7][8][9][10][11]. The phenomenological theory [12] predicts in a vicinity of T c the Curie-Weiss law for the temperature-dependent static permittivity along the ferroelectric caxis.…”

“…Within the plateau range T c > T > T f ≈ 100 K of the ferroelectric phase, however, the permittivity remains unusually high and is a rather weakly increasing function of temperature. The peculiar dielectric behavior of KH 2 PO 4 was ascribed to the activity of domain walls [1][2][3][4][5][6][7][8][9] which dielectric contribution freezes out below the freezing temperature T f [2][3][4][5]. The low-frequency dielectric spectrum in the plateau range of KH 2 PO 4 was reported repeatedly to consist of several Debye-like constituents [6][7][8][9].…”

“…The peculiar dielectric behavior of KH 2 PO 4 was ascribed to the activity of domain walls [1][2][3][4][5][6][7][8][9] which dielectric contribution freezes out below the freezing temperature T f [2][3][4][5]. The low-frequency dielectric spectrum in the plateau range of KH 2 PO 4 was reported repeatedly to consist of several Debye-like constituents [6][7][8][9]. From the influence of temperature [9] and electric ac-field amplitude E ac [10], it is now confirmed that the dispersion is related to domain wall motion and should thus clearly be distinguished from central peak phenomena related to impurities [13] and heat diffusion [11].…”
