Towards electrically injected colloidal semiconductor lasers by Thung, Yi Tian

“…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 by Zheng, Yi

“…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. …”

Tracking and detecting objects in image sequence by Wang, Li

“…Then, a so-called “split-merge” approach is proposed to over-segment a foreground region into subregions and then cluster them into a number of object regions by using the proposed boundary based similarity metric. …”

Pnictogen-halide semiconductors for photovoltaics by Liu, P

“…Convolutional Neural Network (CNN) models were used to evaluate the density of pinholes in the scanning electron microscopy images, and the Segment Anything Model (SAM) was used to separate different regions within the images. …”

Towards robust sensing and recognition : from statistical learning to transfer learning by Yang, Jianfei

“…These algorithms can be further applied to improving the generalization abilities of deep models for WiFi-based sensing and visual sensing including object recognition, object detection, sentiment segmentation and person re-identification.…”
