New Publication - Large-scale statistics for threshold optimization of optically pumped nanowire lasers
Arturo’s recent work has been published in Nano Letters [at http://pubs.acs.org/doi/10.1021/acs.nanolett.7b01725 ]. This work was done in collaboration with the group of Professor Chennupati Jagadish at the Australian National University.
In this paper, we describe how automated and high-speed spectroscopy can be applied to nanomaterials to collect sufficient data to apply statistical techniques. Using this approach, we are able to use the inherent spread in parameter space which arises from bottom-up growth techniques to provide pointers to future optimization.
Importantly, we also reveal that for a specific growth of semiconductor nanolasers, we are able to achieve yields of over 50% and lowest pump thresholds of 42μJ/cm2, a record for room-temperature near infra-red nanolasers.
