Using a combination of temperature and pressure dependence measurements, we investigate the relative importance of recombination processes in InGaAs-based QW lasers. We find that radiative and Auger recombination are important in high quality InGaAs material. At 1.5μm, Auger recombination accounts for 80% Ith at room temperature reducing to ~50% at 1.3μm and ~15% at 980nm. We also find that Aug...

By combining multiple electron coincidence detection with ionization by synchrotron radiation, we have obtained resolved spectra of the OCS(3+) ion created through the double Auger effect. The form of the spectra depends critically on the identity of the atom bearing the initial hole. High and intermediate level electron structure calculations lead to an assignment of the resolved spectrum from...

Photoelectron-Auger electron coincidence spectroscopy is a powerful tool for the investigation of Auger decay processes with different core-ionized intermediate states. In this paper we describe an investigation into the Auger decay of the O2 molecule, with the purpose of bringing new insight into the dynamics of the core hole decay mechanism. Using a novel experimental approach to measuring su...

In this article, the temperature behavior of output power of superluminescent light-emitting diode (SLED) by considering the effect of non-radiative recombination coefficient, non-radiative spontaneous emission coefficient and Auger recombination coefficients has been investigated. For this aim, GaN pyramidal quantum dots were used as the active region. The numerical method has been used to sol...

PURPOSE Technetium-99m (99mTc) has been widely used as an imaging agent but only recently has been considered for therapeutic applications. This study aims to analyze the potential use of 99mTc Auger electrons for targeted tumor radiotherapy by evaluating the DNA damage and its probability of correct repair and by studying the cellular kinetics, following 99mTc Auger electron irradiation in com...

We present the first investigation of excited state dynamics by resonant Auger–Meitner spectroscopy (also known as Auger spectroscopy) using nucleobase thymine an example.

The NVV Auger spectrum from a clean W(lOO) surface has been measured in the second derivative, d N(E)I dE , mode to enhance fine structure. This measurement is compared with spectra generated from both the self-convolution of the tungsten valence-band bulk density of states (obtained from a relativistic APW energy band calculation) and a "restricted convolution" in which only transitions involv...

The measurements were performed on the clean 2 x 1 reconstructed Si(100) surface and this surface exposed to molecular oxygen (0,) or nitric oxide (NO) at room temperature. The data were corrected for electron loss and spectrometer distortions using our newly developed deconvolution method. This method which uses global approximation and spline functions can overcome several difficulties with r...
