Stoichiometric edges during the intrinsic growth of hexagonal boron nitride on Ir(111) Open

Bene Poelsema, Harold J. W. Zandvliet, Arie van Houselt · 2019

The growth of hexagonal boron nitride, hBN, on Ir(111) at 1150–1200 K by thermal decomposition of borazine has been monitored in situ by means of low energy electron microscopy, LEEM. A major and unexpected hBN growth induced transformatio…

Quantum size stabilization of nanofilms on Ge(001) Open

Bene Poelsema, Ali Safaei, Raoul van Gastel, Harold J. W. Zandvliet, Arie van Houselt · 2019

The electronic and structural properties of a Ge-Pt alloy film on Ge(001) were studied with low-energy electron microscopy. Well above 1000 K, a bulklike eutectic film forms, followed by the emergence of an ordered Ge3Pt alloy upon solidif…

Polar edges and their consequences for the structure and shape of hBN islands Open

Bene Poelsema, Adil Acun, Lisette Schouten, Floor Derkink, Martina Tsvetanova , et al. · 2019

The ionic component of the strong bond in hexagonal boron nitride (hBN) has been grossly disregarded in literature. Precisely this quantity is demonstrated to govern the shape of monolayer hBN islands grown at high temperatures. HBN zigzag…

Critical vacancy density for melting in two-dimensions: the case of high density Bi on Cu(111) Open

Raoul van Gastel, Arie van Houselt, Daniel M. Kamiński, Elias Vlieg, Harold J. W. Zandvliet , et al. · 2018

The two-dimensional melting/solidification transition of the high density [2012] phase of Bi on Cu(111) has been studied by means of low energy electron microscopy (LEEM). This well defined phase has an ideal concentration of one Bi atom p…

Chemical vapor deposition growth of bilayer graphene in between molybdenum disulfide sheets Open

Wojciech Jacek Kwiecinski, Kai Sotthewes, Bene Poelsema, Harold J. W. Zandvliet, Pantelis Bampoulis · 2017

Direct growth of flat micrometer-sized bilayer graphene islands in between molybdenum disulfide sheets is achieved by chemical vapor deposition of ethylene at about 800 °C. The temperature assisted decomposition of ethylene takes place mai…

Ordinary and supernumerary resonant scattering of low energy electrons from the BiCu<sub>2</sub>(111) surface alloy Open

Bene Poelsema, M. S. Altman, Raoul van Gastel, Harold J. W. Zandvliet, Arie van Houselt · 2016

Electron intensity versus energy curves from the ordered substitutional BiCu2(111)-surface alloy, obtained with low energy electron microscopy (LEEM), show distinct unexpected intensity dips under normal incidence conditions. The dips abov…

Erratum: Structural and Electronic Properties of Germanene on[Phys. Rev. Lett.<b>116</b>, 256804 (2016)] Open

L. Zhang, Pantelis Bampoulis, А. Н. Руденко, Qirong Yao, Arie van Houselt , et al. · 2016

This corrects the article DOI: 10.1103/PhysRevLett.116.256804.

Structural and Electronic Properties of Germanene on Open

Lijie Zhang, Pantelis Bampoulis, А. Н. Руденко, Qirong Yao, Arie van Houselt , et al. · 2016

To date germanene has only been synthesized on metallic substrates. A metallic substrate is usually detrimental for the two-dimensional Dirac nature of germanene because the important electronic states near the Fermi level of germanene can…

Oxidized Gold as an Ultrathin Etch Resist Applied in Microcontact Printing Open

Ruben B. A. Sharpe, Dirk Burdinski, Jurriaan Huskens, Harold J. W. Zandvliet, Bene Poelsema · 2016

In this report it is described how a gold surface can be treated with an oxygen plasma to become an effective etch mask, with its etch resistive properties based upon electrostatic repulsion. Such a treated gold layer is only temporarily s…

Visualization of steps and surface reconstructions in Helium Ion Microscopy with atomic precision Open

Latent heat induced rotation limited aggregation in 2D ice nanocrystals Open

Pantelis Bampoulis, Martin Herman Siekman, E. Stefan Kooij, Detlef Lohse, Harold J. W. Zandvliet , et al. · 2015

The basic science responsible for the fascinating shapes of ice crystals and snowflakes is still not understood. Insufficient knowledge of the interaction potentials and the lack of relevant experimental access to the growth process are to…
