High critical current densities (J sub c > 10 sup 4 A/cm sup 2 at 77K) in bulk YBA sub 2 Cu sub 3 O sub 7 superconductors processed by melt- textured-growth (MTG) method result from a near-perfe
In practical high-field filamentary superconductors based on A15 compounds, flux pinning sites are usually grain boundaries and the critical current density is found to be inversely proportional to
Two-electrode DFB lasers show promise for combining high speed and frequency tunability for FDM-FSK networks.
We report the measurements of Frequency Modulation (FM) response of InGaAsP buried heterostructure distributed feedback lasers and the system performance of a 1.7 Gb/s and a 622 Mb/s incoherent Fre
The relation of the FM terminals to the over-all TH system is dpscribed briefly in a previous paper.
We have measured the FM and FSK responses of tunable two-electrode DFB lasers up to ~1 GHz.
We have investigated the process latitude and resolution limit of printing contact windows using a high numerical aperture KrF stepper and attenuated phase shift mask (APSM).
Reduced feature dimensions in microelectronic devices has led to a growing reliance on the focused ion beam (FIB) for scanning electron microscopy (SEM) and transmission electron microscopy (TEM) s
The application of thin semiconductor layers as etch masks for high vacuum lithography is described.
A secondary ion mass spectrometer has been added to a liquid metal ion source instrument which was designed as a micro- machining apparatus.
