Aluminum and gold coated quartz crystal oscillators were bombarded by 7 keV Ga+ and then exposed to fairly low pressures (∼1 mTorr) of dimethyl gold hexafluoroacetylacetonate [denoted Me2Au(hfac) ] at room temperature for several hours. While unirr

Ion beam induced deposition of carbon films has been studied as a function of temperature and pressure for both 2‐bromo vinyl benzene and 2‐bromo ethyl benzene. In contrast to recently published results involving vinyl and ethyl benzene, depositi

Evidence is presented for a second condensed phase of excitons in unstressed, high-purity Ge, based on a simple plasma line-shape analysis. Above the critical temperature for electron-hole liquid condensation (T c ≃7 K), time-resolved photoluminesc

The application of focused ion beams to the repair of defects in x‐ray masks is described. An image of the defective region on the mask is obtained using the ion beam in a manner analogous to a scanning electron microscope. Opaque defects are remov

The absorption of phonons by the electron-hole liquid (EHL) in semiconductors has proven to be the principal process causing macroscopic transport of droplets of this Fermi fluid. A characterization of the phonon absorption for frequencies of several

Sufficiently intense photoexcitation of semiconductors produces initially continuous, extended regions of high-density electron-hole plasma. Recent observations in Ge at low temperatures (T=2 K) suggest that these large regions rapidly fragment to fo
