AnnealSys
Annealsys introduces the Zenith 100 high temperature rapid thermal processing furnace that can process 100 mm wafers up to 2000°C. The process chamber with low inertia heating elements allows performing fast annealing processes at high temperature for generation of graphene by sublimation or by CVD and for implantation annealing of silicon carbide wafers.

Tescan Orsay Holding
Newly developed in a consortium joining companies Orsay Physics, Riber SA and laboratories CNRS IM2NP and LAAS, NanoSpace is a dual-beam microscope intended to be directly connected to any MBE system. It allows in-situ surface characterization, direct nano-machining in ultra-clean UHV environment. The direct connection permits a re-start of the growth in the MBE chamber after FIB patterning or high resolution observation. [More]

GaN films and GaN/AlGaN quantum wells grown by plasma assisted molecular beam epitaxy using a high density radical source
Y. Cordier et al.
The achievement of thick high quality GaN films with a high growth rate and low temperature technique is an advantage for integration with other materials. In this view, new high density nitrogen radical sources (HDRS) are developed to provide the necessary features for the plasma MBE growth of GaN. In this paper, we study the behavior of an inductively coupled plasma HDRS and the resulting material properties. [Full abstract] [Online article]

In-Plane Si Nanowire Growth Mechanism in Absence of External Si Flux
S. Curiotto et al.
Here we report on a new mechanism of solid-liquid-solid (SLS) nanowire formation: a liquid eutectic droplet AuSi deposited on a Si substrate captures Au from a vapor, spontaneously moves on the surface resulting in the formation of a Si nanowire behind the moving droplet.

Kinetics and Energetics of Ge Condensation in SiGe Oxidation
T. David et al.
In this study, we address the mechanism of formation of Ge-rich layers and we determine the major driving forces of the enrichment process. We highlight the particular role played by the Si_0.5 Ge_0.5 which is stabilized for various experimental conditions and strain levels. [Full abstract] [Online article]

Quantum Hall resistance standard in graphene devices under relaxed experimental conditions
R. Ribeiro-Palau et al.
Here, we demonstrate that the experimental conditions necessary for the operation of devices made of high-quality graphene grown by chemical vapour deposition on silicon carbide can be extended and significantly relaxed compared with those for state-of-the-art GaAs/AlGaAs devices. [Online article]

Job Opportunities / Research

PhD Position
Title: "Theoretical study of the growth of core-shell nanowires"
Laboratory: INSP, Pierre et Marie Curie University, Paris, France
Key words: Nanowire, Growth, Elasticity, Molecular Beam Epitaxy
The goal of this thesis is to study theoretically the growth of core-shell nanowires.
To describe core-shell nanowires, one will first characterize the elastic interactions. This may be done using a decomposition over the appropriate eigenfunctions of the equilibrium equations with appropriate boundary conditions. The description of the instability within a linear framework will be done analytically. The evolution of the surface at large time, where quantum dots arise on the shell, will then be investigated using possibly one or two frameworks. [More]

The young researcher will take part in the experimental validation and in the development of the ultrahigh vacuum FIB platform, and on the demonstration of its capabilities when coupled to the MBE system. Gain in process cleanliness and pattern positioning accuracy will be demonstrated and compared to ex situ patterning processes. [More]
