Abstract: The recombination lifetime of minority carriers is a critical parameter in semiconductor devices such as photovoltaic cells since it controls the efficiency of such devices. Many techniques have been developed to accomplish recombination measurements and thereby test semiconductor devices' efficiencies. Recombination lifetime average values differ according to semiconductor device type; thus, choosing an appropriate technique is important. This paper studies the concept of excess minority carrier lifetime and its calculations. It also investigates the advantages, limitations, and cap

Charge carrier scattering channels in graphite bridging its valence and conduction band offer an efficient Auger recombination dynamic to promote low energy charge carriers to higher energy states.

Abstract We investigate carrier recombination mechanisms in heavily aluminum (Al) doped p-type 4H-SiC, a material crucial for power devices. The recombination mechanisms in Al-doped p-type 4H-SiC have remained unclear, with reports suggesting various possibilities. To gain insights, we employ photoluminescence (PL) measurements, particularly time-resolved PL (TR-PL), as they are well-suited for studying carrier lifetimes in heavily Al-doped p-type 4H-SiC. We examine the temperature and excitation intensity dependencies of TR-PL and PL spectra and discuss the underlying recombination mechanisms

The extraction of photogenerated charge carriers (photo-CELIV) allows one to independently investigate relaxation of both the mobility and density of photogenerated charge carriers.

Ge/SiGe quantum wells (QWs) are a new system characterized by optical and electronic properties different from those commonly observed in the more widely studied QWs based on III-V semiconductors. These peculiar properties are due to the type-I band alignment for both the Γ- and the L-type states and to the small energy distance between the direct and the indirect bad gap in Ge, which provides Ge/SiGe QWs with a so-called quasi-direct optical behavior. Moreover, these systems are of potential interest for the integration of good optical properties on the CMOS platform: indeed, room temperature

Abstract:
The modern InGaN technology demonstrates high efficiencies only in the blue spectral region and low current operation modes. The growth of InGaN quantum wells (QWs) on nonbasal crystallographic planes (NBP) has potential to deliver high-power blue and green light emitting diodes and lasers. The emission properties of these QWs are largely determined by the localization of carriers in the minima of spatially inhomogeneous band potential, which affects the recombination dynamics, spectral characteristics of the emission, its optical polarization and carrier transport. Understanding it is crucial

The carrier recombination rates in GaAs1 and strained InGaAs/GaAs single-quantumwell lasers have been studied using the differential carrier-lifetime technique for carrier densities from 1017-1019/cm3. We have found that the carrier lifetime is not an intrinsic property of the material but is strongly structure-dependent. Under high levels of excitation, the recombination rates deviate considerably from the recombination rules of the bulk materials. The rates are typically smaller in quantum wells that have lower potential barriers and/or thinner well widths. The rates increase sublinearly wit
