Fabrication of biodegradable and flexible transistor arrays by Cai, Yu Chao

“…In this project, the author uses the biopolymer, knows as Lignin, from the woody plant as gate insulator layer of the organic thin film transistors (OTFTs). The Lignin polymer showed good performance for the transient property and flexibility. …”

Directional emission from electrically injected exciton-polaritons in perovskite metasurfaces by Wang, Yutao, Tian, Jingyi, Klein, Maciej, Adamo, Giorgio, Ha, Son Tung, Soci, Cesare

“…Here a high-finesse metasurface cavity is monolithically patterned in the channel of a perovskite light-emitting transistor to induce a large Rabi splitting of ∼200 meV and more than 50-fold enhancement of the polaritonic emission compared to the intrinsic excitonic emission of the perovskite film. Moreover, the directionality of polaritonic electroluminescence can be dynamically tuned by varying the source-drain bias, which induces an asymmetric distribution of exciton population within the transistor channel. …”

Role of ex-situ HfO2 passivation to improve device performance and suppress X-ray-induced degradation characteristics of in-situ Si3N4/AlN/GaN MIS-HEMTs by Dalapati, Pradip, Li, Hanchao, Arulkumaran, Subramaniam, Ng, Geok Ing

“…Furthermore, due to the generation of chemical vacancies under X-ray, a band tail near the edge of valence band maximum in Si3N4 and HfO2 films can be created. The obtained results suggest that MIS-HEMT fabricated with an atomic layer deposited (ALD)-HfO2 (MIS-HEMT B) has relatively greater performance compared to MIS-HEMT fabricated without ex-situ HfO2 (MIS-HEMT A) according to the higher maximum drain current (Idmax), peak transconductance (gmmax) and lower current collapse, denoting the effectiveness of ALD-HfO2 to passivate the surface traps. …”

Dynamics and stability of evaporating and condensing liquid layers by Wei, Tao

“…The prediction and control of interfacial instabilities are crucial in vapor-liquid systems, such as rupture of thin films in heat exchangers of electric devices. The present work concerns the nonlinear dynamics and stability of evaporating and condensing layers over a horizontal substrate, focusing on the effects of various interrelated physics on the gas-liquid interface. …”
