We report on the fabrication and modification of a top-down nanofabrication platform for enormous parallel silicon nanowire-based devices. We explain the nanowire formation in detail, using an additive hybrid lithography step, optimising a…

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…

Evaporation of Dilute Sodium Dodecyl Sulfate Droplets on a Hydrophobic Substrate Open

Wojciech Kwieciński, Tim Segers, Sjoerd van der Werf, Arie van Houselt, Detlef Lohse , et al. · 2019

Evaporation of surfactant-laden sessile droplets is omnipresent in nature and industrial applications such as inkjet printing. Soluble surfactants start to form micelles in an aqueous solution for surfactant concentrations exceeding the cr…

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…

Spatially resolved electronic structure of twisted graphene Open

Qirong Yao, Rik van Bremen, Guus J. Slotman, Lijie Zhang, Sebastiaan Haartsen , et al. · 2017

We have used scanning tunneling microscopy and spectroscopy to resolve the spatial variation of the density of states of twisted graphene layers on top of a highly oriented pyrolytic graphite substrate. Owing to the twist a moire pattern d…

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…
