A passively Q-switched waveguide laser operating at 1.054 υm has been demonstrated in a Nd-doped phosphate glass. The channel waveguide was fabricated by K-ion
Tunneling spectroscopy of sulfur- and oxygen-terminated n- and p-type GaAs (110) surfaces is reported for air and ultrahigh-vacuum conditions. Simulations of
At this time the twelve documents that make up the initial release of the Standard for the Exchange of Product Model Data (known as STEP) have been sent to the
It is recognized that profiling techniques have been widely used in industry and academic research for manufacturing control and functional control of surface
This is the last part in a series of reports describing a comprehensive study of parameters to characterize three-dimensional surface topography. In conjunction

We have analysed scanning tunnelling microscopc (STM) images of self-assembled didodecylbenzene (DDB) molecules physisorbed on graphite from a DDB solution
We report calculations of electron inelastiv mean free paths (IMFPs) of 50-2000 eV electrons for a group of 14 organic compounds: 26-n-paraffin, adenine, β
