2. Nucleation
Studying Physics in Stuttgart being 18 years old
Theorem No 1: Uli is smart (Avoided military!)
1968 First close interaction with H. Föll (Quantum Theory Exercise)
Theorem No 2: Uli is smarter than I (and probably you)
Theorem No 3: Uli is generous and shares.
The Mozart incident
Theorem No 4: Made snotty but irrefutable remarks all his life.
2. Nucleation
1974
Nucleation concluded.
Random walk starts.
Uli definitely confused
if not inebriated.
Or just newly wed?
3. Scattering
Scattering centers: 1. The females of the species (weak until 1974)
Theorem No 5: Uli is a motivator. Get’s people do do what he
wants and to enjoy it!
First strong scattering
trapping center:
Julia Gösele (+ Andrea Gösele after
phase separation)
3. Scattering
First example of major non-scattering event!
PhD in May 75
Married,
with child
Psi (= psychic power) helps:
Kraution (= cabbage-ion
= Crowdion) discovered
Weak scattering

past

Random walk in Schönbuch Forest
Theorem No 6: Uli Gösele is a great friend and one should always
heed his advice
3. Scattering
Theorem No 7: Uli Gösele, when facing tough problems, comes up
with unconventional solutions that often work (but
may not always find the approval
ofpages
the timid).
> 150
Theorem No 8. He always knew what his priorities were.
3. Scattering
Do you understand that we will turn 30 years
old in a few month? We now need only to
persevere for about another 30 years, then we
will have made it.
Theorem No 7: Uli Gösele, when facing tough problems, comes up
with unconventional solutions that actually work but
may not always find the approval of the timid.
Theorem No 8. He always knew what his priorities were.
Theorem No 9. Uli Gösele always looked ahead and does long-term
planning.
3. Scattering
Second example of momentous non-scattering event in 1979 !
Theorem No 7: Uli Gösele, when facing tough problems, comes up
with unconventional solutions
Once more!
In March (1979) I applied with tremendous effort + presentation
for a “professorship” at the technical School here. I’m on second
place and number one accepted. My topic was “Acoustic
protection against external noise”; I did learn quite a bit about
walls, shutters containers, ….
3. Scattering
Next major scattering center:
The Yu Tan
Once more!
IBM Yorktown Heights
3. Scattering
• No major scattering from 1981 - 1984
(not possible in 1-dim Crowdion space)
• Instead strong non-linearities
around Habilitation in 1980
Habilitation-hat???
3. Scattering
Next major scattering center:
Siemens / Munich
Arno
Schmidt
Move to Munich without (increased) family
Uli still wanted to become a Professor!
3. Scattering
Next major scattering center:
Siemens / Munich
and H. Föll
(third time!)
We did not only
drink beer:
More important:

Uli gets

V. Lehmann
“Goethe und die
Theoretische
Elektrotechnik“
3. Scattering
That
hurt!
3. Scattering
We just got the first patent on porous Si for active
semiconductors. I hope that the effort will pay off.)
(Letter from Nov. 3rd, 1992
That really hurt!
No!
3. Scattering
Last scattering event to be investigated here:
U. Gösele (in Halle) and H. Föll (in Kiel) scatter once more:
Photonic Crystal Initiative
Theorem No 7: Uli Gösele, when facing tough problems, comes up
with unconventional solutions that actually work but
may not always find the approval of the timid.
Theorem No 10: Uli Gösele has a way with friends and people and is
a shrewd judge of character.

Theorem No 8. Uli knows what his priorities are.
Theorem No 9. Uli always looked ahead and does long-term
planning (like his retirement)

No! My metrics that I will announce with full confidence in the
correctness of my own judgment are:
Uli about H. Föll
4. Diffusion Length
A rather large number of people came out of that
encounter as better scientists if not better and
happier people
I’m one of them!
Uli - Thanks for having been my friend and
colleague for many years in the past!
(and, I hope, for many years to come)

Best Wishes!
