The atomic structure at the epitaxial CaF sub 2/Si(111) interface has been determined using high resolution electron microscopy.

We have investigated novel nonlinear conduction properties in K sub (0.30) sub MoO sub 3 at temperatures below 40K.

We have observed two different rf resonances in the frequency dependent real diagonal conductivity of very high quality two-dimensional electron systems in the high magnetic field insulating phase

We report sup (63) Cu nuclear spin-lattice relaxation data for Ba sub 2 YCu sub 3 O sub (7-delta) in the superconducting state obtained by nuclear quadrupole resonance in zero applied magnetic fiel

Measurements of the penetration length lambda of c-axis oriented thin films of YBa sub 2 Cu sub 3 O sub x in magnetic fields H as high as 14 T enable a determination of the transition T sub c (H) b

The temperature dependent Resistance and Magneto- resistance of 2 nm- 20 nm thick CoSi sub 2 films have been measured to a temperature of 200 mK.

From emissometry measurements in lightly doped Si at elevated temperatures we have observed an anomalous absorption band in the wavelength range of 1-5 microns.

Synchrotron radiation has been employed to measure 73 fractional order surface Bragg reflections.

For filling factors nu in the range between 4.16 and 4.28, we simultaneously detect two resonances in the real diagonal microwave conductivity of a two-dimensional electron system (2DES) at low tem

Conductance measurements are reported for quantum dots fabricted by pattern-dependent oxidation in silicon; the small size of these devices allows observation of single electron behavior to tempera
