Best Practices for First-Principles Modeling of Amorphous Oxide Semiconductors: A Statistical Framework and Application to Zn-Sn-O
Michiel J. van Setten, Tonglin L. Newsom, Christopher Pashartis +3
Ternary and quaternary amorphous oxide semiconductors have many properties that make them promising candidates for use in electronic applications like display, memory, and back end…
Impact of Mechanical Stress on IGZO TFTs: Enhancing PBTI Degradation
K. Vishwakarma, K. Lee, A. Kruv +8
This study investigates the impact of out-of-plane compressive mechanical stress (MS) on the performance and reliability of n-channel IGZO thin film transistors (TFTs). It is demon…
Size Effect on Raman Measured Stress and Strain Induced Phonon Shifts in Ultra-Thin Film Silicon
Christopher Pashartis, Michiel J. van Setten, Geoffrey Pourtois
The fabrication of complex nano-scale structures, which is a crucial step in the scaling of (nano) electronic devices, often leads to residual stress in the different layers presen…
Computing Elastic Tensors of Amorphous Materials from First-Principles
C. Pashartis, M. J. van Setten, M. Houssa +1
Advancements in modern semiconductor devices increasingly depend on the utilization of amorphous materials and the reduction of material thickness, pushing the boundaries of their…
