“…However, thermal treatment of the DPSi layer undergoes significant morphological changes, converting small pores into larger ones and simultaneously generating tensile strain, as already reported in our previous study [9]. The morphological changes that DPSi undergoes are crucial in semiconductor fabrication processes, such as epitaxial layer transfer [15][16][17][18][19], making it an excellent alternative and a promising candidate for fabricating electronic devices and solar cells [20][21][22].…”

Previous investigations into SiGe alloys using Raman spectroscopy have generated significant uncertainties regarding the relationships between shifts in Raman peak frequencies and stress. Furthermore, these studies did not establish precise correlations when examining alloys on porous substrates. These substrates have emerged as promising candidates in the highly competitive field of adaptable substrates for epitaxial growth of heterogeneous systems (such as III-V, SiGe, etc.) on Silicon (Si). Among these porous materials, double porous silicon (DPSi) has recently garnered attention, featuring a low porosity upper layer atop a buried high porosity layer. However, during a heat treatment, the upper low-porosity layer transforms into a quasi-monocrystalline Si layer, making it suitable for high-quality epitaxial growth. In this work, we present the first investigation of the vibrational properties of the Si1-xGex membranes grown on top of annealed DPSi, using Raman spectroscopy. We systematically propose new relationships linking the Raman peak shift to Ge concentration and strain, using a set of experimental equations derived from the peak positions of the Si-Si, Si-Ge, and Ge-Ge modes.

“…Importantly, nanomembranes offer a number of additional advantages for nanophotonic applications, unrelated to their optical behavior but still very useful for their practical application in photonics. These include their relatively facile transferability to any arbitrary substrates and supports/handlers [ 47 , 48 ], their self-healing properties [ 49 ] where the nanomembrane spontaneously repairs itself, most usually based on cross-linking within the nanomembrane structure, their extreme stretchability, flexibility and foldability [ 50 ], the possibility of 3D sculpting [ 51 , 52 ], antifouling properties [ 53 ], etc. Most of them are used to impart multifunctionality to nanophotonic elements and devices.…”

“…Regarding the use of photonic nanomembranes in photonic structures not belonging to any of the previously described classes, Aouassa et al utilized transferable nanomembranes to fabricate solar cells [ 48 ]. The team functionalized 30 nm thin silicon nanomembranes by growing InAs/GaAs quantum dots directly on their surface.…”

Nanomembranes are the most widespread building block of life, as they encompass cell and organelle walls. Their synthetic counterparts can be described as freestanding or free-floating structures thinner than 100 nm, down to monatomic/monomolecular thickness and with giant lateral aspect ratios. The structural confinement to quasi-2D sheets causes a multitude of unexpected and often counterintuitive properties. This has resulted in synthetic nanomembranes transiting from a mere scientific curiosity to a position where novel applications are emerging at an ever-accelerating pace. Among wide fields where their use has proven itself most fruitful are nano-optics and nanophotonics. However, the authors are unaware of a review covering the nanomembrane use in these important fields. Here, we present an attempt to survey the state of the art of nanomembranes in nanophotonics, including photonic crystals, plasmonics, metasurfaces, and nanoantennas, with an accent on some advancements that appeared within the last few years. Unlimited by the Nature toolbox, we can utilize a practically infinite number of available materials and methods and reach numerous properties not met in biological membranes. Thus, nanomembranes in nano-optics can be described as real metastructures, exceeding the known materials and opening pathways to a wide variety of novel functionalities.
