Hurtado-Gallego, Juan (author), van der Poel, S. (author), Blaschke, Matthias (author), Gallego, Almudena (author), Hsu, C. (author), López-Nebreda, Rubén (author), Mayor, Marcel (author), Pauly, Fabian (author), Agraït, Nicolás (author), van der Zant, H.S.J. (author)Break-junction techniques provide the possibility to study electric and thermoelectric properties of single-molecule junctions in great detail. These techniques rely on the same principle of controllably breaking metallic contacts in order to create single-molecule junctions, whilst keeping track of the junction's conductance. Here, we compare...journal article 2024

Brandt, John (author), Goyal, N. (author), Moroney, Matthew (author), Janaskie, Sophie (author), Hsu, Angel (author)Research on the economic burden of air pollution has focused primarily on its macroeconomic impact. However, as some studies have found that air pollution can lead to avoidance behavior–for example, reducing the time spent outdoors–we hypothesize that it can also influence consumer spending activity. We combine high frequency data on ozone and...journal article 2024

Volosheniuk, S. (author), Bouwmeester, D. (author), Hsu, C. (author), van der Zant, H.S.J. (author), Gehring, Pascal (author)Thermocurrent flowing through a single-molecule device contains valuable information about the quantum properties of the molecular structure and, in particular, on its electronic and phononic excitation spectra and entropy. Furthermore, accessing the thermoelectric heat-to-charge conversion efficiency experimentally can help to select...journal article 2023

Colombi, G. (author), Boshuizen, B. (author), Chaykina, D. (author), Hsu, Y. (author), Schreuders, H. (author), Savenije, T.J. (author), Dam, B. (author)At ambient conditions, rare-earth oxyhydride thin films show reversible photochromism and photoconductivity, while their mechanism and relation are still unclear. In this work, this question is explored with in situ time-resolved measurements of both optical and transport properties of Gd-based oxyhydride thin films. It is found that p-type...journal article 2023

Montellà, E. P. (author), Chauchat, J. (author), Bonamy, C. (author), Weij, D. (author), Keetels, G.H. (author), Hsu, T. J. (author)In submerged sandy slopes, soil is frequently eroded as a combination of two main mechanisms: breaching, which refers to the retrogressive failure of a steep slope forming a turbidity current, and instantaneous sliding wedges, known as shear failure, that also contribute to shape the morphology of the soil deposit. Although there are several...journal article 2023

(author), El Abbassi, M. (author)Creating a good contact between electrodes and graphene nanoribbons (GNRs) has been a long-standing challenge in searching for the next GNR-based nanoelectronics. This quest requires the controlled fabrication of sub-20 nm metallic gaps, a clean GNR transfer minimizing damage and organic contamination during the device fabrication, as well as...journal article 2023

Hsu, C. (author), Gehring, P. (author), van der Zant, H.S.J. (author)As the miniaturization of electronics continuously progresses, harvesting and generating thermoelectric energy with high efficiency become a key concept to integrate. Theoretical studies suggest that single-molecule devices are ideal candidates for thermoelectric devices with unprecedentedly high efficiencies. Such advantage is achieved by...poster 2022

Hsu, C. (author), Costi, Theo A. (author), Vogel, David (author), Wegeberg, Christina (author), Mayor, Marcel (author), van der Zant, H.S.J. (author), Gehring, P. (author)Probing the universal low-temperature magnetic-field scaling of Kondo-correlated quantum dots via electrical conductance has proved to be experimentally challenging. Here, we show how to probe this in nonlinear thermocurrent spectroscopy applied to a molecular quantum dot in the Kondo regime. Our results demonstrate that the bias-dependent...journal article 2022

(author), Hsu, Cheng Chih (author), Chien, M.P. (author)Single-cell proteomics has the potential to decipher tumor heterogeneity, and a method like single-cell proteomics by mass spectrometry (SCoPE-MS) allows profiling several tens of single cells for >1,000 proteins per cell. This method, however, cannot link the proteome of individual cells with phenotypes of interest. Here, we developed a...journal article 2022

Hsu, Angel (author), Wang, Xuewei (author), Tan, Jonas (author), Toh, Wayne (author), Goyal, N. (author)Although cities have risen to prominence as climate actors, emissions’ data scarcity has been the primary challenge to evaluating their performance. Here we develop a scalable, replicable machine learning approach for evaluating the mitigation performance for nearly all local administrative areas in Europe from 2001-2018. By combining publicly...journal article 2022
