Pictures in "Minor" Publications
Below are some auxiliary pictures concerning the Si . siicide interfaces.
Some of these pictures are simply unpublished but interesting, some other were used in what I called "minor" publications
     
 
Si suilicide Interface TEM
Fig. 3 in "minor" publication No. 36
Micrograph and diffraction pattern of Pt67Si33 after annealing at 200, 350, and 550 oC for 30 min. (a), (b), (c), respctively
 
Si suilicide Interface TEM
Fig. 4 in "minor" publication No. 36
XTEM micrographs of Pt-Si alloys on Si
A) Pt67Si33 after annealing at 350 oC for 30 min.
B) Pt67Si33 after annealing at 3'550 oC for 30 min.
C Pt55Si45 after annealing at 350 oC for 30 min.
The strings of tiny white dots are the topic of interest,

NiSi on S. The sample was annealed at 400 0C.
   
 

Auxiliary Pictures
Below are some auxiliary pictures concerning Si - siicide interfaces.
     
 
HRTEM Si - Pd2Si interface
I'm very attached to that picture. It is, after all, the very first high-resolution picture of a heterogeneous interface. Taken with the Siemens Elmiskopp 102 at Cornell University.
 
HRTEM Si - Pd2Si interface
As above; enlarged part.
 
HRTEM Si - Pd2Si interface
Last one
 
HRTEM Si - Ni silicide interface
Auxiliary picture to Fig. 36 in "lost" book.
 
HRTEM Si Ni silicides
Auxiliary picture to Fig. 38 in "lost" book
We see NiSi at the top and probably Ni2Si at the bottom
 
HRTEM Si - NiSiSi interface
Auxiliary picture to "lost book" Fig. 37 and Ni BNi silicide paper Fig. 12.
The full size picture of the epitaxial interface with a large misfit and an unbelievable density of misfit dislocations.
Another "first" of its kind
 
HRTEM Si - NiSiSi interface
Auxiliary picture to "Silicid Interface" Fig. 8
Shown is epitaxial but twinned NiSi2on a Si substrate.
 
HRTEM Si - NiSiSi interface
Auxiliary picture to "Lost book" Fig. 35
Same as above but no twinning in this case.
 
HRTEM Si - NiSiSi interface
Auxiliary picture to "Lost book" Fig. 36
Three dark lines=rthree interfaces=cutting throug 2 h facteson the way down
 
HRTEM Si - NiSiSi interface
Auxiliary picture to "Lost book" Fig. 27; Ni silicide Fig. 13.
 
TEM Si - NiSiSi interface
Auxiliary picture to Ni silicide Fig. 15.
The NiSi2 is mostly twinned, there are a few small islands with a direct epitaxial relation.
The change in background contrast must be due to small tilt angles at different faces.
 
Silicdes on clean /oxidized Si
Auxiliary Fig. to the "oxide" paper. .
Comparing the formational PtSi on skightly oxidized and clean Si substrates
 
TEM Si - NiSiSi interface
Auxiliary picture to Fig. 15 in the Ni silicide paper.
Shows the twinned (dark) and untwinned patches.
 
XTEM specimen
Auxiliary Fig. to Fig. 3 in the the "lost book".
An actual XTEM specimen. In the middle we have essentially an epoxy bridge with tiny
pieces of Si / silicide still adhereng. That might be enough for HRTEM.#
4 more places might provide thin enough areas
 
Pt55Si45 on Si
Auxiliary picture showing Pt55Si45 on Si, reacted at some temperature.
Compare "minor" publication No. 36.
