    At this year’s FMS Grad Conference, held on September 28, 2024, our Physics PhD and Master’s students showcased their research through both poster and oral presentations. Notably, students from the Master of Science in Materials Physics (MSMP) program participated in the poster session, presenting some remarkable results and achievements.

    This event highlighted the depth of research being conducted within FMS and the strong community spirit of our graduate students.

  • Physics Seminar – Patrick Clancy on what we can learn about new materials using neutron beams

    What can we learn about new materials using neutron beams?
    Neutron beams are an incredibly powerful tool for materials research, providing a unique window into the structure and dynamics of novel materials. In particular, the fundamental properties of the neutron (mass, charge, spin) make it an ideal probe for studying magnetism (e.g. quantum materials and superconductors), bulk properties (e.g. structural materials and industrial components), and materials rich in light elements (e.g. biological membranes, batteries, and hydrogen storage materials). However, there are very few facilities in North America which provide access to neutron beam research techniques. In this talk, I will describe our ongoing efforts to build a new neutron user facility at the McMaster Neclear Reactor, a 5MW research reactor based at McMaster University. I will also highlight several recent examples of how we can use neutron beams to investigate the structural and magnetic properties of copper-based quantum magnets and high Tc superconductors.

    Photonic Quantum Computing: Finding Science behind the Engineering
    There is currently a race to build useful quantum devices, such as quantum computers or quantum communication systems, which promise to accomplish certain tasks in a way that classical systems cannot. For example, companies such as Google and IBM are pursuing quantum computers based on superconducting qubits, while Psi Quantum and Xanadu are attempting the same with photonic devices. In this presentation, I will review the physical requirements of quantum computing and discuss the pros and cons of the photonic approach. While some aspects of realizing a full-scale photonic quantum computer are well-understood and entering the realm of engineering, many interesting scientific questions remain. Some of these topics must be addressed to enable quantum computing, and others are of fundamental interest. To this end, I will present our recent work developing single-photon sources using ultra- thin nonlinear media [1,2], and, if time permits, present a recent line of research exploring alternative models of quantum computation based on superpositions of quantum processes [3,4]. Both of these research directions have potential applications, but they also highlight that the fields quantum information and quantum optics contain many open scientific questions.

  • Physics Seminar – Shengqiang Zhou on Pushing the Tellurium doping limit in Si by ion implantation for infrared optoelectronics

    Pushing the Tellurium doping limit in Si by ion implantation for infrared optoelectronics
    Tellurium is one of the deep-level impurities in Si, leading to states of 200-400 meV below the conduction band.   Non-equilibrium methods allow for doping deep-level impurities in Si well above the solubility limit, referred as hyperdoping, that can result in exotic properties, such as extrinsic photo-absorption well  below the Si bandgap [1]. The hyperdoping is realized by ion implantation and pulsed laser melting. We will present the resulting optical and electrical     properties as well as perspective applications for infrared photodetectors. With increasing the Te concentration, the samples undergo an insulator to metal transition [2]. The electron concentration obtained in Te-hyperdoped Si is approaching 1021 cm-3 and does not show saturation [3]. It is even higher than that of P or As doped Si, and mid-infrared localized surface plasmon resonances (LSPR) are also observed [4]. Using Te-doped Si, we demonstrate the room-temperature operation of infrared photodetectors with both vertical and planar device geometries (see Figure 1) [5,6]. The key parameters, such as the detectivity, the bandwidth and the rise/fall time, show competitiveness with commercial products. To understand the microscopic picture, we have performed Rutherford backscattering/channeling angular scans and hard x-ray spectroscopies [4, 7]. The Te-dimer complex sitting on adjacent Si lattice sites is the most preferred configuration at high doping concentration. Those substitutional Te-dimers are effective donors, leading to the insulator-to-metal transition, the non-saturating carrier concentration as well as the sub-band photoresponse. Our results are promising for the integration of active and passive photonic elements on a single Si chip, leveraging the advantages of planar CMOS technology.
