oil drops can be held stationary by an electric field of suitable strength.The rise and descent times measured for a charged droplet, the electric field voltage setting and readings for various relevant parameters, temperature, viscosity and pressure, are displayed on the touch-sensitive screen.
In the 284–287 eV energy region, corresponding to transitions from the carbon core level to π* orbitals, the spectral shape of the 1L crystal slightly deviates from that of the 2L crystal, exhibiting a more pronounced peak at lower incident angles. To understand the origin of the ...

摘要:We examine transport and relaxation dynamics of optically excited electrons in GaAs-based heterostructure layers, involving dilute nitrides in percent-level concentration range. Such heterostructures contain materials with very different mobilities. Drift instead of Hall mobility is determined usi...
