Addressing individual ferromagnetic nano-objects for magneto-transport measurements

Laboratoire de Physique et Chimie des Nano-Objets, Toulouse


One year post-doctoral position starting in January 2018.

The major goal of our project is the investigation of the electronic and magnetic properties of individual single crystalline ferromagnetic Co nanorods (diameter of 6-7 nm, length of 70-100 nm) and Fe nanocubes (8 - 25 nm edge) elaborated by chemical routes. Until now, electronic and magnetic studies of those magnetic nano-objects (MNO) are carried on assemblies which not allow to probe their intrinsic properties. Even in highly diluted systems we have shown that the dipolar interactions hide the intrinsic magnetic anisotropy [1]. Thus, in order to probe individual MNO, we propose:

  • to develop individual MNO addressing techniques under controlled atmosphere using an electrospray apparatus inserted in a glove box.
  • to probe the MNO electronic and magnetic properties thanks to magneto-transport measurements at different temperatures (300K-4K) and magnetic field orientation (up to 9T) on one or few MNO trapped between two metallic electrodes.

Concerning the first point, a preliminary work made at the LPCNO has shown the possibility to depose individual MNO (Fe nano-cubes and FeCo nano-sphere) on a SiO2/Si substrate by using an electrospray [2]. It consists in injecting a colloidal solution of MNO into a capillary put at a very high voltage. At the end of the capillary, because of high electrostatic repulsion, mono disperse micro-droplets are emitted into a vacuum chamber where the substrate is inserted. The micro-droplets undergo several Coulomb explosions into the vacuum chamber and form, before reaching the sample, a spray of individual MNO. This technique has to be improved, especially, the deposition parameters and the electrospray apparatus has to be installed into a glove box and coupled with an electro valve allowing to perform sequential deposition.

Concerning the second point, our objective is to connect individual MNO in a transistor configuration between two metallic electrodes, using the Si substrate as a back-gate. To do this, we need to fabricate metallic electrodes separate by a nano-gap ranging from 10nm to 50nm. Recently we develop a process allowing us to fabricate nanogap down to 20-30nm, however the yield is low. The process has to be improved in order to reach 10 nm gap to connect Fe nanocubes.

The development and optimization of those two points should allow us to monitor in real time the trapping of individual or few MNO between the metallic electrodes by measuring the current passing through the metallic electrodes as it has been shown by [3] with a similar set-up.

The postdoc will be in charge of the optimization of the electrospray set-up, especially the installation and instrumentation of the electro-valve. He (she) also will work in close collaboration with chemists in order to improve the preparation of the colloidal solution of MNO. He (she) will be also in charge of the nanofabrication and he (she) will optimize the nanogap process. Then he (she) will develop the protocol allowing to monitor in real time the trapping of MNO between two metallic electrodes.

Candidates should be experimentalists with good skills in physics, micro-nanofabrication and chemistry. Please send resume, publications list and motivation letter.

Post doctoral position: Architecture of an aircraft embedded system, dedicated to the pilot assistance in airport areas



This position is linked to a research project funded by the civil aviation administration in France, coordinated by the LATECOERE company located in Toulouse. This project aims at developing an assistance system for the control of an aircraft in airport areas, provided overall for bad visibility conditions (night, fog, rain…); multi-spectral images are acquired, fused and analyzed in order to create a view both synthetic and realistic of the environment where the aircraft is navigating. This view, augmented by symbolic and textual information, is sent to a monitor in the cockpit, in order to inform the pilot about all potential risk when he controls the aircraft from the parking area until the runway, and reciprocally.

The applicant will be integrated in the RAP research team (Robotics, Action and Perception) in the Robotics department of LAAS-CNRS.


The applicant will participate to the design of the architecture of the heterogeneous system (FPGA, CPU, DSP…) with respect to a functional specification and to critical real-time constraints. An SME partner of the project will develop the hardware system.

The applicant  will have also to understand the image processing algorithms developed in the prototyping step, so that he could propose optimizations required for their implementation on the embedded architecture satisfying the real time constraints.

He will be responsible for the technical management of the project (doc, source code…), for the deliverables and for the technological transfer respecting the rules defined in the project.

With the involved permanent researchers of the RAP team, he will supervise the work of two PhD students or engineers funded by the project for the algorithmic development: image enhancement, filtering, fusion, and interpretation in order to detect objects typical from airport areas. He will guide the choice of  these algorithms with respect to their migration on the physical system, specifically to take advantage from the processing parallelism. He will participate and will coordinate the algorithm migration on the system.

He will participate to the validation works supervised by the project coordinator and by aircraft companies. Validations will be done either with simulations (using HIL method) or in real conditions with a system embedded on an aircraft or a vehicle navigating on the taxiways of an airport.

Finally the applicant will have to interact with the project partners, preparing formal presentations for internal meetings and workshops. He will also participate to the scientific dissemination with the RAP permanent researchers.

  • State of the art and contributions on the match between physical architecture and algorithms for real-time vision.
  • Monitoring of the algorithmic development in C/C++
  • Low level optimization and migration of algorithms on a heterogeneous architecture selected to respect real-time constraints.
  • Hardware specification (operators, memories, bus, etc)
  • Project management (doc, source code, meetings, etc)

Applicants must have a PhD in embedded system, electronics…

All of some of these competences will be appreciated:

  • Autonomy, team work, supervision
  • Project management and communication
  • Algorithms for real time vision (OpenCV, Matlab), with basic knowledge in projective geometry (camera model, calibration, homography…)
  • Embedded software  development (C, optimization SIMD NEON)
  • Hardware  development  (VHDL, Xilinx Vivado, test-bench programming)
  • Migration of real-time vision algorithms on heterogeneous architectures FPGA+CPU.
  • Methodology for the design of heterogeneous system.
