- 1. Appl. Phys. Lett. 89, 122112 (2006) , “Interface states for HfO2/Si structure observed by x-ray photoelectron spectroscopy measurements under bias”, Osamu Maida, Ken-ichi Fukayama, Masao Takahashi, Hikaru Kobayashi, Young-Bae Kim, Hyun-Chul Kim, and Duck-Kyun ChoiA 1.0 nm silicon nitride (SiN) layer can prevent reaction between HfO2 and Si completely. In this case, the interface state spectra obtained from x-ray photoelectron spectroscopy measurements under bias have two peaks above and below the midgap, attributable to Si dangling bonds...

- 2. Appl. Phys. Lett. 88, 193502 (2006) , “Role of oxygen vacancy in HfO2/SiHfO2/Si(100) interfaces”, D.-Y. Cho, S.-J. Oh, Y. J. Chang, T. W. Noh, R. Jung, J.-C. LeeWe have investigated the interface states in HfO2/SiO2/Si(100) systems that were prepared by using the in situ pulsed laser deposition technique. X-ray photoelectron spectroscopy data revealed that when the HfO2 film thickness exceeds 11 Å, the film... (Read more)
- 3. J. Appl. Phys. 100, 064501 (2006) , “Introduction of defects into HfO2 gate dielectrics by metal-gate deposition studied using x-ray photoelectron spectroscopy and positron annihilation”, A. Uedono, T. Naito, T. Otsuka, K. Shiraishi, K. Yamabe, S. Miyazaki, H. Watanabe, N. Umezawa, T. Chikyow, Y. Akasaka, S. Kamiyama, Y. Nara, and K. YamadaThe impact of TiN deposition on thin HfO2 films formed on Si substrates was studied using x-ray photoelectron spectroscopy and a monoenergetic positron beam. For the predeposition sample, the positrons implanted into Si were found to diffuse toward the HfO2/Si interface under... (Read more)
