GPU-based commonsense reasoning for real-time query answering and multimodal analysis
Published 2017“…Secondly, in order to reason and retrieve information on rule-based knowledge bases, the thesis introduces gSparql, a fast and scalable inference and querying method on mass-storage RDF data with rule-based entailment regimes. Our approach accepts different rulesets and executes the reasoning process at query time when the inferred triples are determined by the set of triple patterns defined in the query. …”

Dimensionality-dependent type-II Weyl semimetal state in Mo₀.₂₅W₀.₇₅Te₂
Published 2022“…Here, by selecting a special sample with the thickness gradient across two- (2D) and three-dimensional (3D) regime, we show strong evidences that Mo$_{0.25}$W$_{0.75}$Te$_{2}$ is a type-II Weyl semimetal by observing the following two dimensionality-dependent transport features: 1) A chiral-anomaly-induced anisotropic magneto-conductivity enhancement, proportional to the square of in-plane magnetic field (B$_{in}$$^{2}$); 2) An additional quantum oscillation with thickness-dependent phase shift. …”

Ultrafast dynamics in quantum materials probed by time-and-momentum-resolved techniques
Published 2024“…Coherent phonons and CDW systems are two of the richest playgrounds in the ultrafast regime. I am going to investigate various cases where an ultrafast laser pulse decodes the intertwined degrees of freedom in quantum materials. …”

Sociospatial reframing of walking through inclusive streets and urban heritage
Published 2020“…The inclusive street design regime was also found to be compatible with the notion of urban heritage in a meta-narrative review to explore the potential of urban heritage being repositioned for urban and transport planning in which the promotion of walking is a high priority. …”

Design of a supply- and temperature-invariant capacitive sensor interface for low power applications
Published 2015“…Most importantly, the CDC should operate in an ultra-low power regime. Since the full-scale capacitance change of practical capacitive sensors is limited, the CDC has to achieve sensing resolutions of several femto-farads. …”

Near-IR and mid-IR (1.55 μm – 2 μm) silicon photonics devices on silicon-on-insulator (SOI) platform
Published 2018“…Furthermore, the mid-infrared (MIR, 2-15 μm) band is also very crucial as many gases and molecules have unique absorption fingerprints in this regime. Hence there is enormous interest in practical realization of passive and optoelectronic devices operating in the MIR range, including optical sensing and environmental monitoring, free-space communications, bio-medical and thermal imaging. …”

Dynamics and stability of evaporating and condensing liquid layers
Published 2018“…With the 1.5-sided model, a regular non-rupture stable pattern is found in the Rayleigh–Taylor unstable layer due to local evaporation and condensation in the diffusion-limited regime. This is in sharp contrast to the prediction of the one-sided model without the convective and diffusive effects of vapor, where local rupture always occurs in finite time. …”

Towards electrically injected colloidal semiconductor lasers
Published 2025“…The NPL-VCSEL demonstrated a low lasing threshold of 21.6 W cm-2 with a single-mode Q-factor of 11800 under continuous-wave (cw) excitation, with good agreement between the cw-pumped lasing spectra and the ps pulse-pumped lasing spectra. to highlighting the NPL-VCSEL’s robustness under different optical pumping regimes, I demonstrated the NPL-VCSEL’s performance under continuous wave optical pump, affirming the suitability of the colloidal NPLs as the preferred gain medium to realize the desired electrically injected colloidal semiconductor lasers. …”

Studies on plasma assisted molecular beam epitaxial growth of GaN-based multilayer heterostructures on Si for photodetector application
Published 2019“…Tunability of band gap and the possibility of formation of heterostructures with group III-nitride materials allow the design of complex structures to detect both UV and infra-red (IR) spectral regimes (multi band) on a single chip. By growing AlGaN/GaN multiple quantum well layers, IR detector can also be obtained, which means IR and UV detector can be achieved using the same material. …”
