Особенности разряда на границе раздела твердых слоистых диэлектриков
Установлена связь величины разрядного напряжения на границе раздела твердых слоистых диэлектриков от длины разрядного расстояния. Обнаружено явление заглубления канала разряда в диэлектрик, прилегающий к границе раздела, выход его на внешнюю поверхность с последующим развитием по воздуху
Microminiaturized, biopotential conditioning system (MBCS)
Multichannel, medical monitoring system allows almost complete freedom of movement for subject during monitoring periods. System comprises monitoring unit (biobelt), transmission line, and data acquisition unit. Belt, made of polybenzimidizole fabric, is wrapped around individual's waist and held in place by overlapping sections of Velcro closure material
Excited states in bilayer graphene quantum dots
We report on ground- and excited state transport through an electrostatically
defined few-hole quantum dot in bilayer graphene in both parallel and
perpendicular applied magnetic fields. A remarkably clear level scheme for the
two-particle spectra is found by analyzing finite bias spectroscopy data within
a two-particle model including spin and valley degrees of freedom. We identify
the two-hole ground-state to be a spin-triplet and valley-singlet state. This
spin alignment can be seen as Hund's rule for a valley-degenerate system, which
is fundamentally different to quantum dots in carbon nano tubes and GaAs-based
quantum dots. The spin-singlet excited states are found to be valley-triplet
states by tilting the magnetic field with respect to the sample plane. We
quantify the exchange energy to be 0.35meV and measure a valley and spin
g-factor of 36 and 2, respectively
