Recombination processes in intrinsic and p-doped low-threshold 1.3 µm InAs-based quantum dot lasers on silicon
<p>Data for the paper with the following abstract.</p> <p>On-chip lasers are a key component for the realization of silicon photonics. The performance of silicon-based quantum dot (QD) devices is approaching equivalent QDs on native substrates. To drive forward design optimization we investigated the temperature and pressure dependence of intrinsic and modulation p-doped 1.3 μm InAs dot-in-well (DWELL) laser diodes on on-axis silicon substrates for comparison with devices on GaAs substrates. The silicon-based devices demonstrated low room temperature (RT) threshold current densities (<em>J<sub>th</sub></em>) of 192 Acm<sup>-2</sup> (538 Acm<sup>-2</sup>) intrinsic (p-doped). Intrinsic devices exhibited temperature stable operation from 170-200 K. Above this, <em>J<sub>th</sub></em> increased more rapidly due to increased non-radiative recombination. P-doping increased the temperature at which <em>J<sub>th</sub>(T)</em> started to increase to 300 K with a temperature insensitive region close to RT, but with a higher <em>J<sub>th</sub></em>. A strong correlation was found between the temperature dependence of gain spectrum broadening and the radiative component of threshold <em>J<sub>rad</sub>(T)</em>. At low temperature this is consistent with strong inhomogeneous broadening of the carrier distribution, which is more pronounced in the p-doped devices. At higher temperatures <em>J<sub>th</sub></em> increases due to homogeneous thermal broadening coupled with non-radiative recombination. Hydrostatic pressure investigations indicate that while defect-related recombination dominates, radiative and Auger recombination also contribute to <em>J<sub>th</sub></em>.</p>

Binding-mediated direct translocation of HIV-1 Tat-conjugated quantum dots in living cells
<p>Cell-penetrating peptides (CPPs) can translocate across cell membranes, and thus have great potential for the cellular delivery of macromolecular cargoes. However, the mechanism of this cellular uptake process is not yet fully understood. In this study, time-lapse light sheet optical microscopy was implemented to obtain a parallel visualization of the translocating dynamics of individual human immunodeficiency virus 1 (HIV-1) transactivator of transcription (Tat) peptide conjugated quantum dots in complex cellular terrains. Remarkable trajectory aggregates were observed on the cell surface, possibly caused by interaction between the Tat peptides and heparan sulfate groups on the plasma membrane. Spectral-embedding analysis of the trajectory aggregates revealed a manifold formed by isotropic diffusion and directed movement. Further stochastic analysis indicated that the Tat peptides may have remodeled the actin framework in the cytoplasm to reduce their interaction with local membrane environment. The membrane deformation induced by Tat-peptide attachment increased with the disruption of the actin framework, yielding higher interactions on the Tat-coated particle. Characteristic hot spots for interaction were detected on the membrane, suggesting that a funnel passage had formed for the Tat-coated particles. This finding offers valuable insight into the cellular delivery of nanoscale cargoes, suggesting an avenue for direct therapeutic delivery. </p>
