Optimizing Energy-Harvesting Hybrid VLC/RF Networks With Random Receiver Orientation
IEEE AccessThis paper investigates an indoor hybrid visible light communication (VLC) and radio frequency (RF) scenario with two-hop downlink transmission. A light emitting diode (LED) transmits both data and energy via VLC to an energy-harvesting relay node, which

Shubnikov-de Haas oscillations of a single layer graphene under dc current bias
, 2011 Shubnikov-de Haas (SdH) oscillations under a dc current bias are experimentally studied on a Hall bar sample of single layer graphene. In dc resistance, the bias current shows the common damping effect on the SdH oscillations and the effect can be well ...

Resonance Kondo Tunneling through a Double Quantum Dot at Finite Bias
, 2003 It is shown that the resonance Kondo tunneling through a double quantum dot (DQD) with even occupation and singlet ground state may arise at a strong bias, which compensates the energy of singlet/triplet excitation.

Investigation into pulse sequence analysis of PD features due to electrical tree growth in epoxy resin [PDF]
, 2016 Electrical trees developed using point-plane samples have been investigated under three different voltage conditions: AC, AC with positive DC bias, and AC with negative DC bias. Visual observations mainly indicate two types of electrical tree progression
