Project description
Engineered disorder enhances charge carrier transport in nanostructured semiconductors
So-called disordered materials have no long-range order but can have local correlations or order between atoms or molecules. Liquids and glasses are perhaps the best known of these. When it comes to semiconductor materials, particularly nanostructured semiconductor materials, disorder is thought to impede charge carrier transport and most research has targeted minimising it. However, results of recent studies indicate disorder may instead enhance carrier transport. To leverage this possibility, scientists must better understand the relationship between disorder and transport. The ERC-funded EnVision project will develop hyperspectral transient microscopy, a pioneering super-resolution technique able to simultaneously visualise the time, space and energy dimensions associated with the transport of carriers.
Objective
Disorder is generally considered to have a purely negative impact on carrier transport and most efforts aim to minimize it. However, recent studies suggest that disorder may enhance carrier transport via carrier funneling along energetic gradients or promote carrier interconversion at defect sites. Critically though, before disorder can be exploited for improved optoelectronic performance of nanomaterials, a better understanding of the relationship between disorder and transport is needed.
EnVision aims to build a bridge between fundamental observations of the benefits of disorder and materials engineering. To enable this, I have designed a two-fold strategy focussed on 1) defining the detailed design rules for the rational design of disorder driven carrier transport and interconversion, and 2) develop strategies to engineer the local energy landscapes of nanostructured semiconductors that boost carrier transport and interconversion.
To enable the definition of the detailed design rules, I will take the crucial step of developing Hyperspectral Transient Microscopy – the first super-resolution technique capable of simultaneously visualizing the transport of carriers in space, time, and energy. Using metal-halide perovskites as a versatile testbed, EnVision will make critical advances beyond the current state-of-the-art in promoting carrier transport along compositional gradients, boost carrier interconversion at local dopants site, and the creation of on-demand energy landscapes using nanoindentation.
Through its unique approach, EnVision will introduce the concept of functional disorder, paving the way for new formalisms nanomaterial engineering and guiding the realization of fully optimized energy landscapes for optoelectronic and photonic technologies.
