Reducing both the cost and weight of Germanium (Ge)-based devices is a key concern in
extending these technologies to mainstream applications. In this framework, the porous Ge …

Germanium is listed as a critical raw material, and for environmental and economic
sustainability reasons, strategies for lower consumption must be implemented. A promising …

Abstract Bulk Silicon (Si) possesses an indirect bandgap and low surface area to volume
ratio. Porous silicon (PSi), a derived material of Si, overcomes drawbacks of Si, and …

As a widely used semiconductor material, single crystal silicon inevitably suffers from sub-
surface damage in mechanical processing, and the study of stress field generated by …

The Photovoltaic (PV) market is dominated by crystalline silicon materials in the form of high-
quality high-cost Czochralski monocrystalline silicon (mono-Si) and lower-cost defect-prone …

The production of flexible monocrystalline semiconductor thin films less than a few tens of
micrometers in thickness is currently receiving huge interest in various emerging …

Porous silicon and epitaxial thickening is a lift-off approach for silicon foil fabrication to avoid
kerf losses and produce foils with thicknesses less than 50 µm. The crystal quality of the …

Spalling of a brittle semiconductor substrate is an attractive method for fabricating sub-50 μm
thick single crystal semiconductor wafers in large area. Here, a spalling process to fabricate …
