Lateral carrier diffusion can lead to significant smearing in photoluminescence (PL) images of silicon wafers with high lifetime or localised recombination centres. A method to de-smear the PL image by applying the continuity equation in two dimensions has been proposed previously and demonstrated on a virtual wafer with simulated carrier diffusion and artificial random Gaussian noise. This wor...

Plasma-enhanced atom layer deposition (PEALD) can deposit denser films than those prepared by thermal ALD. But the improvement on thickness uniformity and the decrease of defect density of the films deposited by PEALD need further research. A PEALD process from trimethyl-aluminum (TMA) and oxygen plasma was investigated to study the influence of the conditions with different plasma powers and d...

Minority Carrier Lifetime in Beryllium-Doped InAs/InAsSb Strained Layer Superlattices Report Title Minority carrier lifetimes in undoped and Beryllium-doped Type-2 Ga-free, InAs/InAsSb strained layer superlattices (SLS) with energy gaps as low as 0.165 eV were determined from photoluminescence kinetics. The minority carrier lifetime of 450 ns at 77 K in the undoped SLS confirms a high material ...

We demonstrate all-optical logic in a micron-size silicon ring resonator based on the free-carrier dispersion effect in silicon. We show AND and NAND operation at 310 Mbit/s with ~10-dB extinction ratio. The free-carrier-lifetime-limited bit-rate can be significantly improved by active carrier extraction.
