TaN interface properties and electric field cycling effects on ferroelectric Si-doped HfO2 thin films
Patrick D. Lomenzo,Qanit Takmeel,Chuanzhen Zhou,Chris M. Fancher,Eric Lambers,Nicholas G. Rudawski,Jacob L. Jones,Saeed Moghaddam,Toshikazu Nishida +8 more
TL;DR: In this paper, the chemical interface properties of sputtered TaN bottom and top electrodes were investigated with x-ray photoelectron spectroscopy and it was shown that the chemical heterogeneity of the bottom-and top- electrode interfaces gives rise to an internal electric field, where Ta-O bonds at the bottom electrode interface and Hf-N bonds at both electrode interfaces are identified.
Journal ArticleDOI
Ferroelectric phenomena in Si-doped HfO2 thin films with TiN and Ir electrodes
Patrick D. Lomenzo,Peng Zhao,Qanit Takmeel,Saeed Moghaddam,Toshikazu Nishida,Matthew A. Nelson,Chris M. Fancher,Everett D. Grimley,Xiahan Sang,James M. LeBeau,Jacob L. Jones +10 more
TL;DR: In this paper, a Si-doped hafnium oxide with TiN and Ir electrodes has been fabricated in the metal-ferroelectric-insulator-semiconductor (MFIS) structure.
Journal ArticleDOI
Ferroelectric Si-Doped HfO 2 Device Properties on Highly Doped Germanium
Patrick D. Lomenzo,Qanit Takmeel,Chris M. Fancher,Chuanzhen Zhou,Nicholas G. Rudawski,Saeed Moghaddam,Jacob L. Jones,Toshikazu Nishida +7 more
TL;DR: In this article, the Si-doped HfO2 thin films have favorably improved ferroelectric properties on the p+Ge substrate due to the lack of a dielectric interfacial layer between HmO2 and Ge.
Journal ArticleDOI
The effects of layering in ferroelectric Si-doped HfO2 thin films
Patrick D. Lomenzo,Qanit Takmeel,Chuanzhen Zhou,Yang Liu,Chris M. Fancher,Jacob L. Jones,Saeed Moghaddam,Toshikazu Nishida +7 more
TL;DR: The ferroelectric behavior of the HfO2 thin films is shown to be dependent on both the Si mol. % and the distribution of Si-dopants as mentioned in this paper.
Journal ArticleDOI
Annealing behavior of ferroelectric Si-doped HfO2 thin films
TL;DR: In this article, the anneal temperature and time dependence of the ferroelectric Si-doped HfO 2 thin films were investigated by applying 700 −C −900 −C rapid thermal anneals for 5 −s −60 −s durations.
