    • Atomistic modeling of a superconductor–transition metal dichalcogenide–superconductor Josephson junction 

      Nieminen, Jouko; Dhara, Sayandip; Chiu, Wei-Chi; Mucciolo, Eduardo R.; Bansil, Arun (26.05.2023)
      article
      Using an atomistic tight-binding model, we investigate the characteristics of a Josephson junction formed by monolayers of MoS2 sandwiched between Pb superconducting electrodes. We derive and apply Green's function–based ...

    • Edge states in the honeycomb reconstruction of two-dimensional silicon nanosheets 

      Mannix, Andrew J.; Saari, Timo; Kiraly, Brian; Fisher, Brandon L.; Hsu, Chia-Hsiu; Huang, Zhi-Quan; Chuang, Feng-Chuan; Nieminen, Jouko; Lin, Hsin; Bansil, Arun; Hersam, Mark C.; Guisinger, Nathan P. (08.07.2019)
      article
      Electrons confined within a two-dimensional (2D) honeycomb potential can host localized electronic states at their edges. These edge states exhibit distinctive electronic properties relative to the bulk and may result in ...

    • Inter-Layer Coupling Induced Valence Band Edge Shift in Mono- to Few-Layer MoS2 

      Trainer, Daniel J.; Putilov, Alexei V.; Di Giorgio, Cinzia; Saari, Timo; Wang, Baokai; Wolak, Mattheus; Chandrasena, Ravini U.; Lane, Christopher; Chang, Tay-Rong; Jeng, Horng-Tay; Lin, Hsin; Kronast, Florian; Gray, Alexander X.; Xi, Xiaoxing; Nieminen, Jouko; Bansil, Arun; Iavarone, Maria (13.01.2017)
      article
      Recent progress in the synthesis of monolayer MoS2, a two-dimensional direct band-gap semiconductor, is paving new pathways toward atomically thin electronics. Despite the large amount of literature, fundamental gaps remain ...

    • Moiré superlattices and 2D electronic properties of graphite/MoS<sub>2</sub> heterostructures 

      Trainer, Daniel J.; Putilov, Aleksei V.; Wang, Baokai; Lane, Christopher; Saari, Timo; Chang, Tay Rong; Jeng, Horng Tay; Lin, Hsin; Xi, Xiaoxing; Nieminen, Jouko; Bansil, Arun; Iavarone, Maria (05 / 2017)
      article
      &lt;p&gt;Heterostructures of graphite/MoS&lt;sub&gt;2&lt;/sub&gt; display a wide range of lattice registry due to rotational alignment and/or lattice mismatch. Using high resolution scanning tunneling microscopy and ...

    • Proximity-Induced Superconductivity in Monolayer MoS2 

      Trainer, Daniel J.; Wang, BaoKai; Bobba, Fabrizio; Noah, Samuelson; Xi, XiaoXing; Zasadzinski, John; Nieminen, Jouko; Bansil, Arun; Iavarone, Maria (2020)
      article
      Proximity effects in superconducting normal (SN) material heterostructures with metals and semiconductors have long been observed and theoretically described in terms of Cooper pair wave functions and Andreev reflections. ...

    • Spin filtering in silicene by edges and chemically or electrically induced interfaces 

      Saari, Timo; Nieminen, Jouko (05 / 2018)
      article
      &lt;p&gt;Silicene is a graphene-like material with relatively strong spin-orbit coupling exhibiting gapless topologically protected edge states. In addition, it has a buckled structure, and hence, it stands as a feasible ...

    • Visualization of defect induced in-gap states in monolayer MoS2 

      Trainer, Daniel J.; Nieminen, Jouko; Bobba, Fabrizio; Wang, Baokai; Xi, Xiaoxing; Bansil, Arun; Iavarone, Maria (28.02.2022)
      article
      Atomic-scale intrinsic defects play a key role in controlling functional electronic properties of two-dimensional (2D) materials. Here, we present a low-temperature scanning–tunneling microscopy and spectroscopy investigation ...
