Fabrication of green light emitting ZnS:Tb thin film electroluminescent devices using atomic layer epitaxy is described. In this investigation, particular emphasis is placed on the effect of Tb doping profiles and concentrations on the emission characteristics. It is shown that rapid thermal...
A capacitively coupled 13.56‐MHz radio‐frequency (rf) plasma is produced in the presence of a magnetic ring‐cusp field. In order to determine an accurate electron energy distribution function (EEDF) and an electron density by means of Langmuir probe in this rf plasma, an asymmetrical double...
A recent theory establishing the validity of the particle in a box model is illustrated using numerical results for a one‐dimensional nanostructure with atomically abrupt boundaries. The dominant criterion for validity is that the envelope function be slowly varying. The effective mass related...
We present the experimental results on how to suppress self‐mode‐locking in a free‐run or Q ‐switched Nd:YAG laser with intracavity fullerenes. It was demonstrated that the self‐mode‐locking was partly or completely suppressed when a certain sample containing fullerenes, such as C 60...
We report the porous nature of electron‐beam evaporated silicon on the sidewalls of metal‐oxide‐semiconductor field‐effect transistor (MOSFET) gate spacers. This property was used to develop and fabricate submicron elevated source/drain MOSFETs with 200–500 Å ultrashallow junctions....
Pt/Au Schottky contacts on AlInAs lattice‐matched to InP have been fabricated using effective cleaning of the semiconductor surface with low‐energy (30 eV) Ar + ions prior to the metal deposition. A short‐time annealing of the contacts at moderate elevated temperatures in the range of 230...
The temperature dependence of germanium surface segregation during growth by solid source SiGe molecular beam epitaxy (MBE) was studied by x‐ray photoelectron spectroscopy and kinetic Monte Carlo (KMC) modeling. Germanium segregation persisted at temperatures 60 °C below that predicted by a...
A phase‐unifying (PU) mirror as output coupler of unstable resonators applied to high‐gain, short‐pulse XeCl lasers has been realized and tested. A high‐mode volume, nearly diffraction limited beam has been extracted from the XeCl laser by using a PU‐unstable resonator of magnification...
We demonstrate an ultrafast graded‐gap electron transfer optical modulator structure with electron escape times on the order of 1 ps. All other aspects important for high‐speed applications, for example, electroabsorption and electrical behavior remain essentially unaffected.
