in being decided between the multiple bond s and metallic bond, according with
the Table
12.1
synopsis;
The most striking result is provided by the velocity and charge bondon-to-electron
ratios,
ς
v
and
ς
e
, which for all silanes considered achieve in Table
12.3
their maxi-
mum values, 99.9951 [%] and 1, respectively, and identically with those generally
prescribed in Table
12.2
(last row) corresponding with the generic realization of
the actual silanes bondonic radii and bonding energy, although in various real-
izations above and below of those values; nevertheless, the highest velocity and
the identity of the bondonic charge with the electron one, although the bondon
is a bosonization of an electronic pair, strongly suggest the actual silanes chem-
ical bond as being of metallic nature according with the appropriate columns
prescriptions of Table
12.1
;
Finally, the bondonic life time as computed with the specific Eq. (12.7) results in
two order of magnitude higher (i.e. longer times) that the predicted spectroscop-
ically times of Eq. (12.18); this has two important consequences: one is that the
silanes chemical bonding by bondon is this way definitely consecrated as being of
metallic nature since also the last column condition of Table
12.1
is fulfilled; the
second consequence is of experimental nature and gives high hopes that under ap-
propriate time-resolved spectroscopy investigation the longer bondonic lifetime
than the spectroscopic (fluctuation) levels times may lead with the real observa-
tion of the bondonic signal itself so different by that of electronic transition or
chemical bonding vibrations, see also next chapter (Putz et al.
2015b
).
All these bondonic features were unitarily represented in Fig.
12.1
for the silanes
molecules of Table
12.3
: it has a shape classifying it in the class of bondonic varia-
tions with delocalization energy, or with inverse of the transition frequencies for their
(HOMO-LUMO) frontier levels, or among the carbon-based systems with interme-
diate reaction rate at room temperature, see the previous chapter (Putz et al.
2015a
);
all of these highly predicting the silanes compounds as the reliable nano-structures
with high nano-extended properties, by both their metallic and reactivity behavior;
they are therefore recommended as ideal candidate for silicene smart materials, at
their turn replacing in the near future the actual celebrated graphene structures.
