  • PhD position - Lipidic Lyotropic Liquid Crystals for Photonics

    The Adolphe Merkle Institute's Soft Matter Physics Group (Prof. Ullrich Steiner) is accepting applications for one PhD position in the "Lipidic Lyotropic Liquid Crystals for Photonics” project within Dr. Vogler’s Ambizione Fellowship and Bioinspired Photonics subgroup.

    The position:

    This position is part of an SNSF Ambizione project called “Structural Color, the Way Nature Creates It” and is fully funded for four years.

    About the project:

    Structural color is a specific type of color where the color is created by constructive interference from a nanostructure rather than by absorbing pigments. These colors are among the most dazzling in nature, as seen in the Morpho butterfly or in peacock feathers. The goal of this project is to understand how structural color is formed in butterflies and to fabricate it biomimetically. This PhD position focuses on understanding how periodicities in lipidic lyotropic liquid crystals can be boosted to the photonic range. To this end, we will test different hypotheses in the field, including the use of various lipids, phospholipids, glycolipids, and biopolymers. We will characterize the samples using cryo-TEM, small-angle X-ray scattering, scanning electron microscopy, and optical microscopy. Ultimately, this research could lead to the development of biodegradable, non-toxic, brilliant, photonic pigments.

    Requirements:

    • Master’s degree in chemistry, materials science, physics, or related fields.
    • The desire to conduct interdisciplinary research as part of an international team.
    • The ability to independently and collaboratively advance a complex project. In your motivation letter, please describe the projects in which you have participated and whether you worked alone on the project or in a team.
    • Excellent communication and presentation skills.
    • Proficiency in English at the C1 level.
    • Data analysis skills.

    Advantageous:

    • Experience in physical chemistry and/or nanofabrication
    • Some knowledge of optics
    • Nationality from an EFTA/EU state or Swiss
    • Programming skills, preferably in Python

    Procedure:

    Applications will be collected until October 1st, and the selected candidates will be invited for an interview. The start date for the PhD position is December 1 or January 1.

    Please send your CV, motivation letter, and the contact information of at least two references in one PDF file via email to Viola Vogler-Neuling at ami.applications@unifr.ch, with the subject line “PhD LLLCs for Photonics”.

  • Two PhD Positions - Soft Matter Physics Group
    The Adolphe Merkle Institute's Soft Matter Physics Group (Prof. Ullrich Steiner) invites applications for two PhD positions in the "Strong Localisation of Light through the Controlled Assembly of Amorphous Patchy Colloid Networks” project.

    In opaque materials, light is multiply scattered before emerging.  A long-standing interesting fundamental question arises: Is it possible to design a strongly scattering material from which light never emerges? While theoretically predicted and despite several experimental efforts, this effect has not yet been demonstrated.  Our approach follows the theoretical studies, which require an interplay of order and disorder in the arrangement of the scatterers within the material.  

    To this end, we will develop a system of colloidal building blocks that can be assembled into networks, allowing us to adjust the order-disorder interplay of the resulting network. These 3D networks are then replicated into high-refractive index materials (silicon or titania) and optically characterised to achieve strong light scattering. One of the PhD projects concerns the creation of the building blocks, i.e., the synthesis of the colloids and their assembly, while the second will work on replicating the networks as mentioned above.  Both students will also use molecular dynamics and optical simulations to predict promising network morphologies, guiding their experiments.

    Applicants must have a Master’s degree in Chemistry, Materials Science, or Physics and wish to pursue interdisciplinary research in a fast-moving international team. The ability to advance a complex project independently and as part of a team, excellent communication skills, and proficiency in English are key requirements for this position. Experience in polymer or colloid science will be of advantage, and some knowledge of optics is desirable. 

    The Adolphe Merkle Institute offers attractive employment conditions and outstanding infrastructure in a state-of-the-art research facility.
     
    The position will be filled as soon as possible. Please send your CV, motivation letter, and contact information of at least two references as one PDF file via E‐mail to ami.applications@unifr.ch with the subject title “PhD Light Localisation”.
