Thermal Processing Limits in Oxide-Channel Ferroelectric Field Effect Transistors
Lance Fernandes, Yu-Hsin Kuo, Chengyang Zhang +15
In this work, we report a systematic study of the impact of high-temperature post-capping thermal annealing on the memory characteristics of Oxide-semiconductor channel ferroelectr…
Work hardening behavior in a steel with multiple TRIP mechanisms
M. C. McGrath, D. C. Van Aken, N. I. Medvedeva +1
Transformation induced plasticity (TRIP) behavior was studied in steel with composition Fe-0.07C-2.85Si-15.3Mn-2.4Al-0.017N that exhibited two TRIP mechanisms. The initial microstr…
First-principles study of the Mn, Al and C distribution and their effect on the stacking fault energies in austenite
N. I. Medvedeva, M. S. Park, D. C. Van Aken +1
We present ab-initio simulation of manganese, aluminum and carbon impurities in austenite and demonstrate their inhomogeneous distribution, which involves the repulsion of intersti…
Electronic properties of layered multicomponent wide-bandgap oxides: a combinatorial approach
A. Murat, J. E. Medvedeva
The structural, electronic, and optical properties of twelve multicomponent oxides with layered structure, RAMO, where R=In or Sc; A=Al or Ga; and M=Ca, Cd…
Tuning the properties of complex transparent conducting oxides: role of crystal symmetry, chemical composition and carrier generation
Julia E. Medvedeva, Chaminda L. Hettiarachchi
The electronic properties of single- and multi-cation transparent conducting oxides (TCOs) are investigated using first-principles density functional approach. A detailed compariso…
Unconventional approaches to combine optical transparency with electrical conductivity
J. E. Medvedeva
Combination of electrical conductivity and optical transparency in the same material -- known to be a prerogative of only a few oxides of post-transition metals, such as In, Sn, Zn…
