A new type of sesqiterpene lactone isolated from artemisia annua L. arteannuin B
(Elsevier, 1973)
The structure of a new sesquiterpene lactone, arteannuin B, isolated from Artemisia annua L. is reported.
Criteria for the determination of the stereochemistry of steroidal indolizidines
(Elsevier, 1974)
E/F-Indolizidine steroids, which represent a structural unit of Solanum alkaloids, have been synthesized and used to evaluate criteria (IR—Bohlmann bands,1a-c —hydrogenbond,2a-e NMR,3a-c mass spectra,4 kinetic studies of ...
p-n transition capacitance
(Elsevier, 1971)
Quite general expressions for the capacitance of the inhomogeneous semiconductor structures, and not necessarily that of p-n junctions, have been derived starting with the basic concept that this capacitance is defined as ...
Influence of carriers on the capacitance of p-n junctions with deep donors
(Elsevier, 1974)
Applying the definition of p-n junction capacitance [1], which takes into account the effect of carriers in the space-charge region, a sufficiently accurate approximate expression is derived for the low-frequency capacitance ...
Static characteristics of metal-insulator-semiconductor-insulator-metal (MISIM) structures-I. Electric field and potential distributions
(Elsevier, 1975)
The static characteristics (potential and electric field distributions) of sandwich structures of a metal 1-insulator 1-nondegenerated semiconductor-insulator 2-metal 2 (M1I1S I2M2)-type are analyzed. A theory is given ...
Static characteristics of the metal-insulator-semiconductor- insulator-metal (MISIM) structure—II. Low frequency capacitance
(Elsevier, 1975)
It is shown that the reciprocal value of low frequency capacitance of a MISIM structure can be represented by a sum of reciprocal values of insulator layer and surface space charge capacitances and an “interaction” term ...
