Ultrafast trapping times in ion implanted InP

Annealing behaviour of high-dose-implanted nitrogen in InP

Concentration profiles of nitrogen in vacuumannealed pand n-type single-crystal (1 0 0) InP implanted with 1]101630 keV 15N` ions cm~2 have been studied by Secondary Ion Mass Spectrometry (SIMS) and Nuclear Resonance Broadening (NRB) techniques. Damage induced by the nitrogen implantation was studied by Rutherford Backscattering Spectrometry (RBS) and channeling. Annealing the samples led to lo...

An ion-implanted InP receiver for polarization resolved terahertz spectroscopy.

We report on the construction, optical alignment and performance of a receiver which is capable of recording the full polarization state of coherent terahertz radiation. The photoconductive detector was fabricated on InP which had been implanted with Fe(+) ions. The device operated successfully when it was gated with near infrared femtosecond pulses from either a Ti:sapphire laser oscillator or...

Reconfigurable 1×4 InP-based optical switch

An integrated 1 4 InP-based optical switch is reported. The device is quite simple and full device operation is achieved by injecting electrical currents to two electrodes. Since the operation of the switch relies on current spreading, using the carrier-induced refractive index change in InGaAsP multiple quantum wells, an area-selective zinc in-diffusion process is used to regulate the current ...

Titanium Nitride and Nitrogen Ion Implanted Coated Dental Materials

Titanium nitride and/or nitrogen ion implanted coated dental materials have been investigated since the mid-1980s and considered in various applications in dentistry such as implants, abutments, orthodontic wires, endodontic files, periodontal/oral hygiene instruments, and casting alloys for fixed restorations. Multiple methodologies have been employed to create the coatings, but detailed struc...
