The structural properties of epitaxial indium nitride thin films were characterized and related to the mechanical properties as measured by nanoindentation. The seven epitaxial InN films examined were deposited over the temperature range 200–400°C

It has been shown by optical and x‐ray measurements that GaN nucleation layers deposited at 540 °C on (0001)‐oriented sapphire substrates have a measurable crystalline component, although the x‐ray data and the lack of absorbance features near

We have studied the conducting transition metal complex, copper bis-(2,5-dimethyl- N , N ′-dicyanoquinonediimine) (Cu(2,5-DM-DCNQI) 2 ), using scanning tunneling microscopy (STM). The crystal face imaged by STM at molecular resolution shows structu

An extensive investigation of InN overlayers on AlN‐buffered (00.1) sapphire by reactive magnetron sputtering has been undertaken and the dependencies of several basic materials properties (film thickness, development and quality of heteroepitaxy,

The effects of a thin nucleation layer of AlN on the magnetron sputtering growth of InN are investigated in comparison with films deposited onto bare sapphire surfaces. Sapphire substrates were cleaned, vacuum baked and sputter coated with a thin lay

A resonating xylophone bar magnetometer has been utilized as the mixer in a heterodyne detector for variable-frequency alternating magnetic fields. To illustrate the range of this detection scheme, examples offered include the response to low frequen

Single-phase aluminum nitride films were deposited onto fused quartz and single-crystal sapphire by current-controlled, reactive, de magnetron sputtering from an aluminum metal target. Optical and structural properties were observed to correlate syst

A number of multimodal frequency-selective surfaces (FSS) have been fabricated from arrays of unit cells containing two or four, triangular or square, split-ring resonators. In this paper, the underlying physics of the modulation of the spectral inte
