Effective small organic molecule as a defect passivator for highly efficient quasi-2D perovskite light-emitting diodes by Li, Y, Li, F, Yu, Z, Tamilavan, V, Oh, C-M, Jeong, WH, Shen, X, Lee, S, Du, X, Yang, E, Ahn, Y, Hwang, I-W, Lee, BR, Park, SH

“…The small organic molecule can passivate defects on the grain surround and surface of perovskite crystal structures, preventing nonradiative recombination and charge trapping. In this study, a new small organic additive called 2, 8-dibromodibenzofuran (diBDF) is reported and examines its effectiveness as a passivating agent in high-performance green quasi-2D PeLEDs. …”

C-F bond activation by transient phosphenium dications by Đorđević, Nemanja, Tay, Madelyn Qin Yi, Muthaiah, Senthilkumar, Ganguly, Rakesh, Dimić, Dušan, Vidović, Dragoslav

“…Evidence for the existence of transient dicationic species was obtained by trapping the dication 4a2+ with PMe3. According to theoretical analysis, the low-lying lowest unoccupied molecular orbitals of these species were responsible for the observed activation of C–F bonds.…”

Perovskite light emitting transistors by Cheng, Bryan Wei Hao

“…Unfortunately, PeLETs suffer from low brightness and environmental instability related to intrinsic material limitations, such as temperature-activated trapping, ionic motion and polarization effects, which limit device performance and stability at ambient conditions. …”

Blue shift in photoluminescene of semiconductor nanostructures by Khin, San Thit.

“…The bond-order-length-strength (BOLS) correlation indicates that the atomic coordination imperfection causes the remaining bonds of the under-coordinated atom to contract spontaneously associated with bond strength gain and the interatomic trapping potential well depression. This project also involved the study of the entire band structure such as the band gap expansion, core-level shift, Stokes shift (electron-phonon interaction), and dielectric suppression (electron polarization). …”

Organic ferroelectric memory devices based on resistive switching by Damar Yoga Kusuma

“…On the other hand, mutual combination of SAM’s fixed dipole and ferroelectric’s polarizable dipole is employed to realize ferroelectric field effect transistor devices with tailored operational parameters, reduced charge trapping and improved retention stability. The final part of the thesis demonstrates novel organic resistive switching memory concept based on ferroelectric tunnel junction. …”

Silicon nanowires for photovoltaics : from the material to the device by Togonal, Alienor Svietlana

“…Indeed solar cells based on SiNW s benefit from their outstanding optical properties such as extreme light trapping and very low reflectance. In this research project, we have fabricated disordered SiNWs using a low-cost top-down approach named the Metal-Assisted-Chemical-Etching process (MACE). …”

CFD analysis of flow across adjacent buildings with concave roof structure using large-eddy simulation (LES) by Foo, Tze Jie

“…On top of this application, the concave roof structure also provides a method of trapping onto the water instead of letting the rainwater flow down the roof, which can help reduce the chances of flash floods during heavy monsoon seasons. …”

The effects of dub-off angle on chip evacuation in single-lip deep hole gun drilling by Wan, S., Tnay, Guan Leong, Woon, Keng Soon, Yeo, Swee Hock

“…This is demonstrated through a case study on improving the shoulder dub-off design of commercial gun drills, which have a high tendency in trapping chips at the hole bottom. A more effective design criterion for the shoulder dub-off is thus proposed.…”

Atomic-scale mechanisms of defect- and light-induced oxidation and degradation of InSe by Kistanov, Andrey A., Cai, Yongqing, Zhou, Kun, Dmitriev, Sergey V., Zhang, Yong-Wei

“…Moreover, under ambient conditions, the splitting of O2 enables the formation of substitutional (apical) oxygen atomic species, which further cause the trapping and subsequent rapid splitting of H2O molecules and ultimately the formation of hydroxyl groups. …”

Three-dimensional modeling of near-field beam profiles from grating couplers using a deep neural network by Lim, Yu Dian, Tan, Chuan Seng

“…Integrated silicon photonics (SiPh) gratings have been widely studied for the optical addressing of trapped ions. As the formfactor of ion traps reduces, the ion-trapping height decreases, and may unavoidably fall into the reactive near-field region of SiPh gratings. …”

Modeling of functional materials : perovskite solar cells by Aruj Shukla

“…However, for a more holistic analysis of perovskite light harvesters as replacement to the existing TiO2 nano particles, a more nuanced modeling and analysis which incorporates a study of transport properties such as trapping effects (for further spike in efficiency), photo catalytic reaction kinetics and surface & bulk defects (for easier fabrication) is demanded as an integral part of future research plans.…”

Delocalized Davydov D1 Ansatz for the Holstein polaron by Sun, Jin, Duan, Liwei, Zhao, Yang

“…Unique solutions are obtained with the delocalized D1 for different initial conditions when the transfer integral is 20 times the phonon frequency at the zone center, implying the absence of any self-trapping discontinuity. The scaled correlation variance is found to fit satisfactorily well with the predictions of the perturbation theories.…”

Characterising the iron dependence of T-cells by Teh, MR

“…Interestingly, exogenous aspartate substantially rescues the proliferation of iron deprived CD8+ T-cells suggesting that endogenous aspartate sources are unusable, possibly due to trapping of aspartate within the mitochondria. Overall, this thesis demonstrates that iron deprivation impairs T-cell biochemistry at multiple nodes providing insight as to how metabolic and iron modulatory interventions could be coupled to augment or suppress immunity.…”
