Personal profile
Biography
A/Prof. Gilberto A. Umana-Membreno is a Principal Research Fellow at The University of Western Australia (UWA), and a Senior Industry Support Engineer for the Australian National Fabrication Facility (ANFF). His expertise and experience are in the general area of semiconductor optoelectronic and electronic device technology, including device design and modelling, device performance characterisation, failure analysis, reliability-focused device and process design and optimisation, and heterogeneous integration. He currently leads the advanced device design, material/device characterisation/optimisation and integration efforts at the MRG, primarily in infrared sensing materials and devices (HgCdTe). His current research interests also include material and device technology aspects in:
- Infrared sensors/imagers for quantum sensing applications (ultra-high QE, APDs/SPADs)
- Group III-V type-II superlattices, SiGeSn, and InAsSb (infrared photodetectors)
- Electronic transport in nanostructures and novel/emerging semiconductor materials
- Wide bandgap materials and devices (inc. SiC- and GaN-based sensors)
