Atomically Precise Chemical, Physical, Electronic, and Spin Contacts

Paul S. Weiss, California NanoSystems Institute and Departments of Chemistry & Biochemistry, Bioengineering, and Materials Science & Engineering, UCLA, Los Angeles, CA 90095 

Two seemingly conflicting trends in nanoscience and nanotechnology are our increasing ability to reach the limits of atomically precise structures and our growing understanding of the importance of heterogeneity in the structure and function of molecules and nanoscale assemblies. By having developed the “eyes” to see, to record spectra, and to measure function at the nanoscale, we have been able to fabricate structures with precision as well as to understand the important and intrinsic heterogeneity of function found in these assemblies. The physical, electronic, mechanical, and chemical connections that materials make to one another and to the outside world are critical and are intertwined in terms of their function. Just as the properties and applications of conventional semiconductor devices depend on these contacts, so do nanomaterials, many nanoscale measurements, and devices of the future. We discuss the important roles that these contacts can play in preserving key transport and other properties. Initial nanoscale connections and measurements guide the path to future opportunities and challenges ahead. Band alignment and minimally disruptive connections are both targets and can be characterized in both experiment and theory. Chiral assemblies can control the spin properties and thus transport at interfaces. I discuss our initial forays into these areas in a number of materials systems.

Global Opportunities in Nanoscience and Nanotechnology

Paul S. Weiss, California NanoSystems Institute and Departments of Chemistry & Biochemistry, Bioengineering, and Materials Science & Engineering, UCLA, Los Angeles, CA 90095

By having developed the “eyes” to see, to record spectra, and to measure function at the nanoscale, we have been able to fabricate structures with precision as well as to understand the important and intrinsic heterogeneity of function found in these assemblies.

I will discuss the challenges, opportunities, and consequences of pursuing strategies to address both precision on the one hand and heterogeneity on the other. In our laboratories, we are taking the first steps to exploit precise assembly to optimize properties such as perfect electronic contacts in materials. We are also developing the means to make tens to hundreds of thousands of independent multimodal nanoscale measurements in order to understand the variations in structure and function that have previously been inaccessible in both synthetic and biological systems.

Imaging Atomically Precise Chemical, Physical, Electronic, and Spin Interfaces

Paul S. Weiss, California NanoSystems Institute and Departments of Chemistry & Biochemistry, Bioengineering, and Materials Science & Engineering, UCLA, Los Angeles, CA 90095

It has become possible to fabricate atomically precise structures and interfaces. The key to leveraging this capability is to understand the interfacial properties, such as transport, so as to enable optimization in a targeted and reproducible way.1 Ultimately, we would like to be able to predict the structures formed and their properties. I describe a series of advances in atomic-resolution spectroscopic imaging that have moved us closer to this goal. We are able to measure molecular orbitals across interfaces and the conductance of buried contacts.2,3 We are also able to measure buried interactions in molecular layers.4

This latter property has enabled us to measure the atomically resolved structures of biomolecules without averaging.5,6 In all of the above experiments, we exploit sparsity to record and to analyze information-rich data sets. With statistically significant data sets, we are able to understand heterogeneity in structure and function of complex assemblies.

Submolecular resolution spectroscopic imaging for photoactive molecules and assemblies

Paul S. Weiss, California NanoSystems Institute and Departments of Chemistry & Biochemistry, Bioengineering, and Materials Science & Engineering, UCLA, Los Angeles, CA 90095

Rick Van Duyne’s career was built on understanding and leveraging nanoscale interactions of light and fields. Inspired by and building on his work, we have developed and applied new multimodal nanoscale analysis tools based on the scanning tunneling microscope (STM) to measure structure, function, and spectra simultaneously. We are particularly interested in the interactions of photons with precisely assembled structures. We use molecular design, tailored syntheses, intermolecular interactions, and selective chemistry to direct molecules into desired positions to create nanostructures with controlled environments and dimensionality, to connect functional molecules to the outside world, and to serve as test structures for measuring single or bundled molecules and assemblies. The measured results of photoexcitation include photoconductivity, regioselective reaction, intramolecular charge redistribution, and environmental sensitivity. We apply this method to optimize molecules and materials for energy conversion and storage. Concepts from sparsity and compressive sensing are developed and applied to guide efficient data acquisition and to accelerate data analysis and information assembly.

Adding the chemical dimension to lithography: Enabling capture and sensing of signaling molecules, exosomes, and cells

Paul S. Weiss, California NanoSystems Institute and Departments of Chemistry & Biochemistry, Bioengineering, and Materials Science & Engineering, UCLA, Los Angeles, CA 90095

By controlling the exposed chemical functionality of materials from the submolecular through the centimeter scales, we have enabled new capabilities in biology, medicine, and other areas. I will discuss current and upcoming advances and will pose the challenges that lie ahead in creating, developing, and applying new tools using these capabilities. These advances include using biomolecular recognition in sensor arrays to probe dynamic chemistry in the brain and microbiome systems. We also use these and other nanofabrication strategies to develop new tools to catch and to release exosomes and circulating tumor cells for medical diagnostics.

Paul S. Weiss, California NanoSystems Institute and Departments of Chemistry & Biochemistry, Bioengineering, and Materials Science & Engineering, UCLA, Los Angeles, CA 90095

Self-assembled cage molecules offer an opportunity to test chemical and physical properties because within families of molecules, they form identical lattices. Thus, properties such as atomic arrangements within the cage, molecular and surface dipoles, band alignment, and functional group placement can all be controlled. We describe atomic-scale measurements of coordination and valency, dipole, dipole interactions, hydrogen bonding, band alignment, dimensional effects on pKa.
