Item Organic-Inorganic Hybrid Semiconductor Thin Films Deposited Using Molecular-Atomic Layer Deposition (MALD)(Royal Society of Chemistry) Huang, Jie; Zhang, Hengji; Lucero, Antonio; Cheng, Lanxia; KC, Santosh; Wang, Jian; Hsu, Julia W. P.; Cho, Kyeongjae; Kim, Jiyoung; 0000 0003 8600 0978 (Hsu, JWP); 0000-0003-2698-7774 (Cho, K); 0000-0003-2781-5149 (Kim, J); Huang, Jie; Zhang, Hengji; Lucero, Antonio; Cheng, Lanxia; KC, Santosh; Wang, Jian; Hsu, Julia W. P.; Cho, Kyeongjae; Kim, JiyoungMolecular-atomic layer deposition (MALD) is employed to fabricate hydroquinone (HQ)/diethyl zinc (DEZ) organic-inorganic hybrid semiconductor thin films with accurate thickness control, sharp interfaces, and low deposition temperature. Self-limiting growth is observed for both HQ and DEZ precursors. The growth rate remains constant at approximately 2.8 Å per cycle at 150°C. The hybrid materials exhibit n-type semiconducting behavior with a field effect mobility of approximately 5.7 cm² V⁻¹ s⁻¹ and an on/off ratio of over 103 following post annealing at 200°C in nitrogen. The resulting films are characterized using ellipsometry, Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), UV-Vis spectroscopy, transistor behavior, and Hall-effect measurements. Density functional theory (DFT) and many-body perturbation theory within the GW approximation are also performed to assist the explanation and understanding of the experimental results. This research offers n-channel materials as valuable candidates for efficient organic CMOS devices. © 2016.Item Student Haiku Competition entries for 2017(2017-04) Brown, Luke; Crumrine, Ethan; Hussain, Aaly; Manyrath, Alexis; Unnikrishnan, Nikhil; Deen, Rachel; Turner-McCelland, John; Dave, Ajay; Praytor, Stephen; Murai, Britni; Hayes, Garrett; Sampat, Payal; Goldstein, Laura; Dealmeida, Jessica; Rupani, Nishaat; Nguyen, Carolyn; Khorsandi, Sina; Willis, Siloa; Barrios, Yesenia; Akatapo, Solomon; Muñoz, Jessica; Wilson, Jazzmyn; Yu, Ezekiel; Page, Savanna; Haigan, Lucy; Welter, Matthew; Khan, Raheema; Mallari, Joseph; Zhang, Hengji; Prabhu, Amrita; Singh, Archit; Bell, Bethany; Hasan, Ibrahim; Gonzalez, Erik; Reyes, Rebecca; Nwaiwu, Justice; Limaye, Anushka; Sedaghatfar, Emily; Kwon, Adelaide; Poteete, Hannah; Qazi, Dhuha; Qazi, Javariah; Shaikh, Sarah; Bhasker, Bhargavi; Jones, Kiandrah; Juan, Felipe; Chakradeo, Aditi; Eugene McDermott Library.
