Abstract Flexible piezoelectric devices have gained considerable interest due to their potential for new applications, particularly in wearable technology. However, a significant challenge remains measuring low forces on nonplanar and deformable surfaces. Indeed, conformability complex surfaces induces bending stresses the sensors, interfering with measurement of compressive force. Yet such measurements can be valuable, especially medical applications that involve assessing soft tissues....
Abstract Vertical germanium-on-silicon (Ge/Si) avalanche photodiodes offer the advantages of being low-cost, CMOS-compatible and demonstrating high performance for development Short-Wave Infrared (SWIR) sensors telecommunications. Nevertheless, origins dark current noise in Ge-on-Si APDs still need to be clearly identified improve their performance. In this paper, we report study electro-optical characteristics fabricated Avalanche Photo Diodes. A maximum gain 95 was achieved at -33 V on...
Air conditioning systems powered by renewable energies, particularly solar energy, have gained significant attention due to the increasing demand for cooling during heat waves and global emphasis on reducing energy consumption. Among these, absorption refrigeration using H2O-LiBr binary pair offer a sustainable alternative building air conditioning, as they utilize low-grade thermal energy. This study focuses evaluating optimizing thermodynamic performance of single double-effect cycles. By...

Germanium on silicon P-i-N photodetectors fabricated using standard CMOS tools are now successfully used as uncooled detectors in the near-infrared (NIR), which extends from 0.75 to 1.4 μm and short-wave infrared (SWIR), 3 μm. They feature a remarkably high responsivity up 1550 nm low dark current when they operated at reverse biases. The aim is achieve very density with small photodiode pitch. In this paper we discuss fabrication characterization of vertical photodiodes epitaxy Silicon....
The Space Infrared telescope for Cosmology and Astrophysics (SPICA) mission has just been selected by the European Agency as one of three candidate missions to be further studied medium size M5. B-BOP, formerly named POL, is scientific instruments SPICA which aims, among other goals, map galactic filamentary structures their associated magnetic fields.
