In order to investigate the surface states of electron which can tunnel through the sufficiently thin insulator, the electron tunneling spectroscopy is used to measure the tunneling current in function of the bias voltage, and directly to get the sub

Effective mass ratios, m*, of electrons in near intrinsic and n-type Hg 1-x Cd x Te for 0.20 x 0.30 over the temperature range 77 K T 296 K were measured using Faraday rotation spectroscopy. Effective masses were found to be about twice as large at r

We present images of the flux line lattice and spectroscopic measurements of the vortex core region on the as grown (001) surface of an YBa2Cu3O7-(delta ) single crystal at 4.2 Kelvin. These measurements were done in a magnetic field of 6 Tesla appli

The effect of external electric field on the absorption spectra of LiNbO3 crystals doped with Nd3 andCr3 ions has been investigated at 77 K by means of sensitive modulation method. A linear Stark effect isobserved on many lines of Nd3 and on B-lines
