= 1 is insensitive to the site symmetry, because it is parity-allowed.请问这句话是什么意思?
Additionally, parity-forbidden as well as parity-allowed transitions are observed. The breakdown of the parity selection rule is believed to result from ... DC Reynolds,KR Evans,B Jogai,... - 《Physical Review B Condensed Matter》 被引量: 20发表: 1992年 Parabolic quantum wells with the $...
It was observed in the PL spectra that besides the normal "parity-allowed" n=1 electron to heavy hole excitonic transition, le-1hh, there are several relatively weak but unambiguous emission peaks which appear at the high energy side of the dominant le-1hh. The good agreement of the ...

The large difference between the fundamental (independent of allowed/forbidden transition) and the optical (derived from allowed transition) bandgaps renders this double perovskite unsuitable for efficient thin-film photovoltaic applications. Similar parity-forbidden transitions are also found in some other ...
(CAIC), and Cs2AgSbCl6(CASC) that are crystallizing in the cubic structure. However, each of these materials has different optical properties due to direct/indirect bandgap or parity allowed/forbidden transitions that make them distinguishable5,10,11,12. Irrespective of the nature of the bandgap...
all epigenetic processes involving no changes in genes,geneticinformation, orgenetic mechanisms. So, for example, in clear distinction from amphibians, reptiles have evolved a neural control on prostaglandin-induceduterine contractions, which allowed them to speed up parturition that evidently may lead to...
as conditions of supply and demand change. These kinds of adjustment occur naturally if the exchange rates are allowed to fluctuate freely or within wide ranges. If, however, the exchange rates are stabilized or set arbitrarily (as by theBretton Woods Conferenceof 1944) or are set within a na...

This pattern was not necessarily predicted by the continuum hypothesis, but it makes sense in view of the morphology of our study species: producing fruit on multiple branches allowed late-bolting plants to over- come constraints on fruit production related to the growth of the meristem; late-...
