Unconventional structured semiconductors and their applications in optoelectronics and photovoltaics
… of semiconductors are discussed within this thesis: gallium nitride (GaN) and silicon (Si). A novel Pt-assisted electroless etching technique is used to produce porous GaN (PGaN), which is of particular interest for optoelectronics due to its large direct bandgap (3.4 eV). PGaN is also promising …

Development of Small-Pitch, Thin 3D Sensors for Pixel Detector Upgrades at HL-LHC
3D Si radiation sensors came along with extreme radiation hard properties, primarily owing to the geometrical advantages over planar sensors where electrodes are formed penetrating through the active substrate volume. Among them: reduction of the inter-electrode distance, lower depletion voltage …

Multi-layer, Low-crosstalk Integrated Optical Switches
The rapid growth of cloud computing and data-intensive applications necessitates optical switching technologies with ultra-low crosstalk, high bandwidth, and nanosecond-scale reconfigurability. This work presents a comprehensive study of 3D Si-SiN-SiN tri-layer optical switches employing …

Properties and device applications of silicon and silicon-germanium nanostructures with different dimensions
Defect-free crystalline Si/SiGe(Ge) nanostructures are demonstrated despite the 4% lattice mismatch between Si and Ge. The lattice mismatch-induced strain is sufficiently relaxed through the designed, cluster morphology, or nanowire (NW) structures. Future device applications of these nano …

A Multiscale Model for Breast-Conservative Therapy: Computational Framework and Clinical Validation
… work aims to exploit the BCT field developing a 3D patient-specific multiscale model that could predict the breast shape after lumpectomy, from surgery to complete healing. This model consists of two parts: a hyperelastic Neo-Hookean Finite-Element Model of the breast tissues and skin, and a …
