Germanene nanostrips(GenSs)have garnered significant attention in modern semiconductor technology due to their exceptional physical characteristics,positioning them as promising candidates for a wide range of *** exhibit a two-dimensional(buckled)honeycomb-like lattice,which is similar to germanene but with controllable *** modeling of GenSs is essential for developing appropriate synthesis methods as it enables understanding and controlling the growth process of these ***,one can adjust the strip width,which in turn can tune the bandgap and plasmonic response of the material to meet specific device *** this study,the objective is to investigate the electronic behav-ior and THz plasmon features of GenSs(≥100 nm wide).A semi-analytical model based on the charge-carrier velocity of free-standing germanene is utilized for this *** charge-carrier velocity of freestanding germanene is determined through the GW approximation(v_(F)=0.702×10^(6)m·s^(−1)).Within the width range of 100 to 500 nm,GenSs exhibit narrow bandgaps,typi-cally measuring only a few ***,upon analysis,it was found that the bandgaps of the investigated GenSs ranged between 29 and 6 *** well,these nanostrips exhibit√q-like plasmon dispersions,with their connected plasmonic fre-quency(≤30 THz)capable of being manipulated by varying parameters such as strip width,excitation plasmon angle,and sam-ple *** manipulations can lead to frequency variations,either increasing or decreasing,as well as shifts towards larger momentum *** outcomes of our study serve as a foundational motivation for future experiments,and further con-firmation is needed to validate the reported results.
