    Plenary Session

    Controlling the placement and electronic character of dopant atoms in semiconductors lies at the heart of both classical device technology and the emerging field of semiconductor quantum computing. As device dimensions approach the single-atom limit, however, the discrete quantum-mechanical nature of individual dopants demands fundamentally new approaches to fabrication and characterisation....

    Defect Engineering and Metrology

    The continued downscaling of nanoelectronic devices, where performance is governed by nanometer accurate doping distributions, demands metrology solutions with matching spatial resolution. Scanning Spreading Resistance Microscopy (SSRM), an AFM based technique that measures the resistance as current spreads from a high pressure induced β tin phase of silicon beneath a conductive diamond tip,...

    Defect Engineering and Metrology

    Crystalline silicon (c-Si) solar cells are now approaching their fundamental performance limits, with voltages now limited primarily by intrinsic recombination processes. We discuss the key remaining bulk and surface defects relevant for high-efficiency commercial c-Si solar cells, as well as strategies for mitigating these defects in next-generation devices, focusing particularly on work at...

    Group IV for Photonics

    Silicon’s transparency in the telecommunication bands (1260–1625 nm) has traditionally required hybrid integration of materials such as germanium for photodetection, limiting scalability and CMOS compatibility [1-3]. Here, we present a strategy based on ion-beam engineering of deep-level dopants in silicon to realize all-silicon, waveguide-coupled photodetectors operating at room temperature...

    Nitride Semiconductors

    Point defects in gallium nitride (GaN) have recently emerged as a promising platform for room-temperature single-photon generation, exhibiting high emission rates and robust optical properties. GaN also benefits from well-established fabrication processes due to its widespread use in applications such as solid-state lighting and high power and high frequency electronics. Whilst wafers of bulk...
