In this paper, to help reduce the squeal noise produced during the braking of urban railway vehicles, the shape of the disc brake pad was investigated to relieve contact stress. To analyze the disc brake system to identify the source of the squeal no

We report the experimental observation of the UV-visible upconverted luminescence of bulk silicon under pulsed infrared excitation. We demonstrate that non-stationary distribution of excited carriers leads to the emission at spectral bands never to o

We demonstrate the broadband visible luminescence from bulk crystalline silicon and silicon nanoparticles sized 100- 30 nm under near-infrared excitation. We show that the luminescence spectrum has two distinct peaks. The first being centered at 550

Detection of a single nanoparticle on a bare silicon wafer has been a challenge in the semiconductor industry for decades. Currently, the most successful and widely used technique is dark-field microscopy. However, it is not capable of detecting sing

Multi-band valley-protected topological edge states is numerically demonstrated in GaAs-based phononic crystal (PnC) slabs. Two Dirac degeneracies at different frequencies are lifted by rotation of triangular holes in the unit cells breaking the mirr

Valley, as a new degree of freedom, raises the valleytronics in fundamental and applied science. The elastic analogs of valley states have been proposed by mimicking the symmetrical structure of either two-dimensional materials or photonic valley cry

We report the design of GaAs-based monolithic valley phononic crystals (VPnCs) with multiple complete phononic bandgaps, which support simultaneous valley-protected edge states with different symmetries in the gigahertz (GHz) range. Rotation of trian

We measure the spatial distribution of a topologically protected elastic modes in a silica 1D phononic crystal (PnC) by using the photoelasticity imaging technique. The strong localization of the topological elastic mode at the interface of two-joine

We report the design of silica-based 1D phononic crystals (PnCs) with topologically distinct complete phononic bandgaps (PnBGs) and the observation of a topologically protected state of elastic waves at their interface. By choosing different structur

Photonic and phnonic crystals offer the possibilities of controlling light polarization efficiently. Here, we discuss giant optical rotation in a chiral photonic crystal and enhanced photoelastic modulation in a phononic crystal cavity.
