Ti₃C₂ MXene Quantum Dots Synthesis and Applications

Wave particle duality, the wave function, Schrödinger equation, quantum states, operators, superposition and the uncertainty principle form the mathematical and physical foundations for understanding how matter behaves at atomic and subatomic scales. These principles become even more fascinating through the double slit experiment and Schrödinger’s cat, while their engineering significance extends far beyond theory. Atomic spectroscopy, semiconductors, lasers, MRI, nanotechnology and quantum computing all emerge from our ability to understand and apply quantum behavior. From probabilities and wave functions to technologies shaping the modern world, quantum mechanics connects fundamental physics with real engineering innovation. ⚛️🔬 #QuantumMechanics #QuantumPhysics #WaveParticleDuality #SchrodingerEquation #QuantumComputing #Semiconductors

Carnegie Mellon physicists Simranjeet Singh and Jyoti Katoch, along with postdoctoral researchers I-Hsuan Kao and Ravi Kumar Bandapelli, discovered a new form of the Hall effect that produces a measurable response even when a magnetic field is applied in the plane of a material, not just perpendicular to it as long assumed, using ultrathin devices built from tantalum iridium telluride paired with a magnetic layer. Assistant professor Shubhayu Chatterjee provided theoretical modeling explaining how symmetry changes at the material interface enable this unconventional response. Published in Nature Materials, the work suggests a single sensor could eventually detect magnetic fields along multiple axes at once, potentially simplifying sensors used in electronics, transportation, and medical imaging.

Many people ask what the real impact will be of some of the things we’re researching related to quantum materials and quantum technologies, but the truth is that it’s very difficult to predict the future and, specifically, what kinds of technologies will emerge from basic research (which is what we do). For example, in retrospect, it’s possible to trace a timeline that begins with the PhD dissertation of Felix Bloch, Werner Heisenberg’s first doctoral student!, who understood in 1928 how electrons behave as quantum waves and why insulating, metallic, or semiconductor materials emerge, all the way to the invention of the transistor (1947), the microelectronics revolution, and, finally, the entire multibillion-dollar economy of semiconductor chips, digital technologies and AI today, but not the other way around (no one could have predicted this world-changing technology based on an application of those ideas, so novel at the time, regarding quantum mechanics). Nasir Taleb offers a reflection in his fantastic book The Black Swan that I love and that refers to this: “Tools lead to unexpected discoveries, which in turn lead to other unexpected discoveries. But our tools rarely seem to work as intended (...). We build toys. Some of those toys change the world.” #quantum_technologies #blackswan #semiconductors

As we engineer ever smaller technologies, “seeing” what happens inside them becomes increasingly difficult.🧐 🔬As optical devices approach the wavelength of light, conventional optical microscopes can no longer reveal the nanoscale optical fields that govern their behavior. 🖼️The blue patterns below are not images of the nanoparticles, they are images of how light behaves around them. They arise from the interference between incoming and scattered light, forming an optical fingerprint that reveals how single silver #nanoparticle responds to light. 💡Here, we show how these optical fields can be mapped experimentally with an atomic force microscope. The key idea is to use a photothermal response that is often treated as a limitation as the measurement itself. By making optical near-fields experimentally accessible, we can move closer to directly observing how the next generation of #nanophotonics devices works. 👏 Special thanks to Christian Ritz for bringing this work to publication in American Chemical Society #Photonics.

Double-slit experiment on the atomic scale. ⚛️ Researchers from the Universität Tokio, together with Toma Susi's group at #univie, have miniaturized the classic double-slit experiment down to atomic columns in a silicon crystal, using a finely focused electron beam in a scanning transmission electron microscope (STEM). Understanding which vibrations matter most connects atomic motion to macroscopic performance, informing the design of better materials for energy conversion, electronics and #quantum technologies.

Tata Institute of Fundamental Research et al. Review van der Waals Josephson Junctions This work reviews recent advances in Josephson junctions based on van der Waals materials for superconducting devices. The long relaxation times of excited states in 2D heterostructures enable the construction of quantum sensors, with the 2D materials themselves serving as efficient excitation transport buses. The introduction of moiré superlattices and topological effects further expands their potential applications in quantum computing and ultra-sensitive hybrid sensors. Despite the promising outlook, the review identifies scalable fabrication as the key challenge on the path to practical application and provides a forward-looking roadmap. Published August 17 in Nature Reviews Physics.

📄 Pleased to share that our new review article is now available online in Infrared Physics & Technology: "Advancements in Emerging Materials for Visible-to-Infrared Photodetectors: A Comprehensive Review" This work reviews recent progress in photodetectors based on 2D materials, metal-halide perovskites, and colloidal quantum dots — covering detection mechanisms, device architectures, and key performance metrics (responsivity, detectivity, response speed, dark current, spectral range). We also benchmark these emerging technologies against established platforms (Si, InGaAs, HgCdTe) and discuss key challenges toward practical deployment: stability, scalability, wafer-level integration, and CMOS compatibility. Overall, this work aims to provide a critical perspective on how emerging semiconductor materials can contribute to the next generation of visible-to-infrared photodetection and advanced imaging technologies.
