Bouwmeester, D. (author)This dissertation centers around two topics: graphene nanoribbons (GNRs) and superconductors. The aim of this thesis is to work towards combine these two topics, in order to study how superconducting correlations interact with magnetic correlations within graphene nanoribbons, such as the magnetic edge states present in the zigzag edges of...doctoral thesis 2024

Bouwmeester, D. (author), Ghiasi, T.S. (author), Borin Barin, Gabriela (author), Müllen, Klaus (author), Ruffieux, Pascal (author), Fasel, Roman (author), van der Zant, H.S.J. (author)Atomically precise graphene nanoribbons (GNRs) are predicted to exhibit exceptional edge-related properties, such as localized edge states, spin polarization, and half-metallicity. However, the absence of low-resistance nanoscale electrical contacts to the GNRs hinders harnessing their properties in field-effect transistors. In this paper, we...journal article 2023

(author), van der Zant, H.S.J. (author), Castellanos Gomez, A. (author)The field emission (FE) properties of TiS3 nanosheets and nanoribbons, synthesized by direct sulfuration of bulk titanium, are investigated. The nanosheets show an enhanced FE behavior with a low turn-on field of ∼0.3 V/μm, required for drawing an emission current density of ∼10 μA/cm2. Interestingly, the TiS3 nanosheet emitter delivered a...journal article 2023

(author)Atomically precise graphene nanoribbons (GNRs) are a promising emerging class of designer quantum materials with electronic properties that are tunable by chemical design. However, many challenges remain in the device integration of these materials, especially regarding contacting strategies. We report on the device integration of uniaxially...journal article 2021

Dumitru, Florin-Silviu (author), Cucu Laurenciu, N. (author), Matei, Alexandru (author), Enachescu, Marius (author)McCulloch-Pitts neuron structures are comprised of a number of synaptic inputs and a decision element, called soma. In this paper, we propose a 5-bit Graphene Nanoribbon (GNR)-based DAC to fulfill the role of the summation element featuring programmable input weights. The proposed GNR-based 5-bit DAC relies on: (i) GNR unit current cells and ...journal article 2021

Jiang, Y. (author)As CMOS feature size is reaching atomic dimensions, unjustifiable static power, reliability, and economic implications are exacerbating, thus prompting for research on new materials, devices, and/or computation paradigms. Within this context, Graphene Nanoribbons (GNRs), owing to graphene’s excellent electronic properties, may serve as basic...doctoral thesis 2020

(author), Sun, Qiang (author), Prechtl, Thorsten (author)Graphene nanoribbons (GNRs) have attracted strong interest from researchers worldwide, as they constitute an emerging class of quantum-designed materials. The major challenges toward their exploitation in electronic applications include reliable contacting, complicated by their small size (<50 nm), and the preservation of their physical...journal article 2020

Heerema, S.J. (author)The information that can be extracted from DNA base sequences, is important for our understanding of biology, for insights in disease, and the way we practice medicine. The technology that one uses to determine DNA-base sequences is called ‘DNA sequencing’. A portable device that enables fast and accurate sequencing, can potentially greatly...doctoral thesis 2018

Heerema, S.J. (author), Vicarelli, L. (author), Pud, S. (author), Schouten, R.N. (author), Zandbergen, H.W. (author), Dekker, C. (author)Many theoretical studies predict that DNA sequencing should be feasible by monitoring the transverse current through a graphene nanoribbon while a DNA molecule translocates through a nanopore in that ribbon. Such a readout would benefit from the special transport properties of graphene, provide ultimate spatial resolution because of the single...journal article 2018

Rondoni, D. (author)Nanotechnology is the field of applied science and technology that aims to manipulate, test and produce devices and systems which have dimensions comparable to the atomic and molecular scale, that is few tens of nanometers and smaller. Amongst the wide range of fields touched by nanotechnology, nanoelectronics is quite a peculiar one. In fact...doctoral thesis 2009
