Stationary Hamiltonian transport with dc bias [PDF]
Europhysics Letters (EPL), 2006 The dynamics of a particle in a symmetric periodic potential under the influence of a time-periodic field is characterized by a mixed phase space with regular and chaotic components. An additional external dc bias transforms the chaotic manifold into a domain with unbounded acceleration.

Pulsed-Dc Bias Magnetron Sputtered Tib2 Ceramic Coating
International Journal of Refractory Metals and Hard Materials, 2023 Titanium diboride, TiB2, is well known as a ceramic material with a hexagonal structure which presents various attractive properties, such as high hardness and excellent corrosion, thermal oxidation, and wear resistance. However, one drawback of TiB2 coatings is their poor adhesion to substrate materials due to high compressive residual stress after ...

Efficient spin injection into graphene through trilayer hBN tunnel barriers [PDF]
, 2018 We characterize the spin injection into bilayer graphene fully encapsulated in hBN using trilayer (3L) hexagonal boron nitride (hBN) tunnel barriers. As a function of the DC bias, the differential spin injection polarization is found to rise up to -60 ...

Reducing AC impedance measurement errors caused by the DC voltage dependence of broadband high-voltage bias-tees [PDF]
, 2007 During the AC impedance characterization of devices, from the kHz-range up to the GHz-range, accuracy can be lost when a DC voltage is applied. Commercial high-voltage broadband bias-tees are often voltage-dependent, which can cause inaccuracies at low ...

An Energy-Efficient ADO-OFDM System for Optical Wireless Communication
IEEE Photonics Journal, 2023 This paper proposes an energy-efficient asymmetrically clipped direct-current (DC) biased optical orthogonal frequency division multiplexing (EEADO-OFDM) scheme, which replaces the fixed DC bias of DC biased optical OFDM (DCO-OFDM) branch with a adaptive

Spontaneous DC Current Generation in a Resistively Shunted Semiconductor Superlattice Driven by a TeraHertz Field [PDF]
, 1997 We study a resistively shunted semiconductor superlattice subject to a high-frequency electric field. Using a balance equation approach that incorporates the influence of the electric circuit, we determine numerically a range of amplitude and frequency ...

Optimal Strategy of Triple Phase Shift Transient DC Bias for Dual Active Bridge DC-DC Converter [PDF]
E3S Web of Conferences, 2020 Under the traditional phase shift control, dual active bridge DC-DC converter (DAB) has a transient bias on the inductance current when the phase shift ratio changes suddenly, which leads to increase in the current stress of switch tubes and even ...
