Coulomb interaction has a striking effect on electronic propagation in one-dimensional conductors. The interaction of an elementary excitation with neighbouring conductors favours the emergence of collective modes, which eventually leads to the destruction of the Landau quasiparticle. In this process, an injected electron tends to fractionalize into(More)
The relationship between the severity of natural freezing and frost damage (FFD) and the observed growth recovery and field production of Superior potatoes (Solanum tuberosum L.) was investigated under screen house conditions. Potato plants were damaged by accidental freezing and frost during the early phase of shoot growth, 40 days after planting in(More)
Based on a long-term investigation of material growth and fabrication procedure, the cryoHEMTs (Cryogenic High Electrons Mobility Transistors) made at the CNRS/C2N (formerly LPN) are now in the process to fill the gap of the FET (Filed-Effet Transistor) for high impedance, low-power and low-frequency deep cryogenic readout electronics. Different input(More)
We report measurements of the rectification of microwave radiation 0.7–20 GHz at the boundary between two-dimensional electron systems created by a narrow gap split gate on a silicon surface for different temperatures, electron densities, and microwave power. For frequencies above 4 GHz and different temperatures, the rectified voltage Vdc as a function of(More)
In order to fill the gap of low-temperature and low-frequency noise field-effect transistors and to meet the needs in various experiments under deep cryogenic conditions, specially designed HEMTs with different gate capacitances have been fabricated and characterized at 4.2 and 77 K. At 4.2 K and with an appropriate gate capacitances, the obtained lowest(More)
The damping sensitivity analysis of interconnected power system low frequency oscillation is studied. The function of sensitivity analysis is implemented in the Small Signal Stability Analysis Package (SSAP). The paper mainly analyzes the sensitivities of oscillation modes with respect to the parameters of power system stabilizer (PSS) in the excitation(More)
Seasonal experiments, spring studies in 2008 and 2014, and autumn studies in 2008 and 2013, were conducted to investigate the nutritional and structural response of potato leaves to reduced nitrogen (N) supply in the nutrient solution. Tissue culture plantlets of cultivars Atlantic and Superior were transplanted into a recirculating aeroponic system and(More)
Summary form only given. In this talk, we show that properly designed 1D-QB conductor can actually lead to voltage-gain. Conceptually, the electric conduction in the 1D-QB conductor can be described by the Landauer-Buttiker formalism in terms of the relative positions between the 1D sub-bands (SB), the electrochemical potential of the source reservoir and(More)
