Growth of beta-FeSi2 films via noble-gas ion-beam mixing of Fe/Si bilayers
(Journal of Applied Physics, 2001)
A detailed study of the formation of beta -FeSi2 films by ion-beam mixing of Fe/Si bilayers with noble gas ions is presented. Fe films of 35-50 nm deposited on Si (100) were irradiated with 80-700 keV Ar, Kr, or Xe ions ...
Amorphous-iron disilicide: A promising semiconductor
(Applied Physics Letters, 2001)
We report here the synthesis and the measurements of the microstructural and optical properties of a promising semiconductor, amorphous-iron disilicide. The material was obtained by ion-beam mixing of Fe layers on Si, with ...

AIDS epidemic at the beginning of the third millennium: time for a new AIDS vaccine strategy
(Vaccine, 2001)
Current expansion of AIDS pandemic significantly accelerates AIDS vaccine research resulting in development and clinical testing of several AIDS vaccine candidates. At the same time, available experimental and clinical ...
Breather induced modification of the speed of sound
(Physical Review Letters, 2001)
The modification of the speed of sound induced by the presence of breathers in a quasi-one-dimensional magnetic chain is examined in the framework of the sine-Gordon model. Within the pseudoharmonic phonon approximation ...
Negative response elements in keratin genes mediate transcriptional repression and the cross-talk among nuclear receptors
(Journal of Biological Chemistry, 2001)
Very little is known about the mechanisms responsible for the findings that binding of nuclear receptors (NR) to some promoter elements leads to transcriptional activation, whereas binding to others leads to repression. ...
