Description

Strain engineering has emerged as a powerful tool for tailoring material properties and enabling novel functionalities beyond conventional approaches. Microhelices and nanomembranes represent a unique class of mechanically engineered structures in which controlled strain induces unprecedented electronic, optical, and mechanical behaviours. By precisely tuning strain, new architectures can be fabricated, giving rise to exciting advancements in both fundamental science and technology. These structures exhibit tunable bandgaps, enhanced piezoelectricity, and chirality-dependent responses, opening new frontiers in photonics, flexible electronics, and energy harvesting. In this talk, I will explore recent advancements in strain-induced property modulation, fabrication strategies, and emerging technological applications. I will discuss how precise control over strain gradients and material heterogeneity in micro- and nanoscale membranes provides opportunities for designing slow-wave helical structures for THz traveling wave tube amplifiers. Additionally, I will also discuss the effects of controlled strain on the energy bandgap modulation of semiconductor nanomembranes.
