Preface
"The frequent
usc
orwell known
critic.11
data handbooks like Beilstein, Gmclin and Landolt·Bornstein
is
impeded by
the fact that only larger libraries - often far away from the scientist's working place - can afford such precious collec-
tions.
To
!>atisfy
an urgent need
of
many scientists working
in
the
field
of
semiconductor physics for having
al
their
working place a comprehensive, high quality, but inexpensive collection
of
at
leasl the basic data
of
their field
of
interest this volume contains the most important data
of
semiconductors.
All
data were compiled from infannation on
semil:onductors presented on more than 6 000 pages in various volumes
oflhe
New Series
of
Landolt-Bomstein,"
With these words the aim
of
the volume "Semiconductors - Basie Data", published
by
the present author -
was
defined
in
the preface to its first Edition. This edition - published
in
two volumes
in
the Series "Data
in
Science and
Technology" - appeared
in
1991/92. The 2nd
!-::<lition
was published
in
one volume five years later,
While preparing the third edition,
it
became clear that a complete revision was necessary for several reasons:
- To the cleven subvolumes
of
volumes IlU17 and
1IU22
of
the New Scries
of
Landolt-Bornstein - published b::.
tween 1982 and 1988 - eight new supplementary subvolumes (lll/41) appeared
in
thc meantime. The
19
volumes
now available comprise about
10
000 pages with more than
13
000 figures. Thus, much new data had to
be
included
in
Ihis collection
of
basic data.
- The Landolt-Bomstein series is now available on the Internet. So easy access to the data via Internet had
to
be
considered
in
the structure
of
this volume.
- Last but
not
least the possibility
10
combine a
primed
medil/m wilh an enclosed
CD~ROM
gives the opportunity
to
improve
t~
value
ofa
data collection by shifting parts
of
the information onto the CD-ROM, thereby increasing the
amount
of
information substantially without an undue increase
of
the number
of
pages.
By
this oppornmity, a drawback
of
earlier editions could
be
eliminated: To limit
the
number
of
pages, a
comprehen~
sive presentation
of
the most important data was only possible
for
the group
IV
and III-V semiconductors. All other
groups
of
scmieonduetors could only be handled very bricfly
in
tabular
form
with a
n-"Stricted
number
of
figures and
without references. This drawback
is
now eliminated. The (printed) volume contains the basic data for llil known
groups
of
semiconductors
in
suitable lenghl. Figures on crystal structures and band structures supplement the tables.
Further information was shifted
to
the CD-ROM:
- Figures. A user
of
this book usually first looks for daln colJecled
in
!abIes. Figures can supply deeper information
by presenting functional dependences, such as temperature dependence, pressure dependence, and by presenting
dispersion curves, optical spectra etc. Such additional information
is
now provided
in
about 1000 additional figures
on the CD-ROM. Presenting these figures
in
the printcd version had required several hundred pages.
- References. The knowledge
of
the origin
of
data
i~
necessary
for
the user
to
find the context
in
which the data were
measured. Thus, data presented
in
this volume should also contain more than 100 pages
of
references. These refer-
ences were shifted
to
the enclosed CD-ROM.
- Addilional information IIseful for the reader but
100
spacious
TO
be presemed ill the
primed
L'ersion.
There are a
large number
of
substances (e.g. boron compounds, transition metal and rare earths compounds) exhibiting "scmi-
conducting properties". A presemation
of
data referring to such substances
in
the printed text seemed to be too
extcn~
sive and was therdore left
to
the CD-ROM
Thus, the present edition differs substantially
from
thc formcr editions
in
the amount
of
information and the manner
of
presentation (and unavoidable also
in
the number
of
pages). To emphasize this change the title
of
the third
ed
ition
has been changed from "Semiconductors: Basic Data" to "Semiconductors: Data Handbook".
I do hope the users
of
the volume will profit
from
these innovations.
