We demonstrate one-dimensional nanobeam photonic bandedge lasers with InGaAsP quantum wells at room temperature from the lowest dielectric band of photonic crystal nanobeam waveguides. The incident optical power at threshold is 0.6 mW (effectively ~18 μW). To confirm the lasing from the dielectric bandedge, the polarization and the photoluminescent spectra are taken from nanobeams of varying la...

We report the observation of a current-driven metal (M)-insulator (I) phase oscillation in two-terminal devices incorporating individual WxV1-xO2 nanobeams connected to parallel shunt capacitors. The frequency of the phase oscillation reaches above 5 MHz for approximately 1 mum long devices. The M-I phase oscillation, which coincides with the charging/discharging of the capacitor, occurs throug...

Linear dynamic response of simply supported nanobeams subjected to a variable axial force is assessed by Galerkin numerical approach. Constitutive behavior is described by three functional forms of elastic energy densities enclosing nonlocal and strain gradient effects and their combination. Linear stationary dynamics of nanobeams is modulated by an axial force which controls the global stiffne...

Based on doublet mechanics theory and various beam theories, this paper presents free vibration of axially loaded zigzag armchair nanobeams. A two-noded higher order element is used to solve the problems nanobeams with boundary conditions. The verification studies in terms fundamental frequencies buckling loads are performed by comparing results present model Molecular Dynamic Simulations, Doub...

   The main purpose of the present investigation is to analyze more comprehensively the size-dependent nonlinear free vibration response of multilayer functionally graded graphene platelet-reinforced composite (GPLRC) nanobeams. As a consequence, both of the hardening stiffness and softening stiffness of size effect are taken into consideration by implementation of the nonlocal str...

The thermal management has been widely focused due to its broad applications. Generally, the deformation can largely tune transport. main challenge of flexible electronics/materials is maintain conductance under large deformation. This work investigates a nano-designed Si metamaterial constructed with curved nanobeams by molecular dynamics simulation. Interestingly, it shows that insensitive (s...

Abstract Bound states in the continuum (BICs) are localized coexisting with extended waves inside continuous spectrum range, which have infinite lifetimes without any radiation. To extract high-Q quasi-BIC resonances from symmetry-protected BIC for practical applications, symmetry-breaking approaches usually exploited, either by slightly breaking excitation field symmetry or structure symmetry....
