I try to read more or less constantly
.
It means peak shift and peak form nature depends of substance but possibility of seen these effects depends of spectral or energy resolution our equipment (crystal type and EPMA machine configuration).
Am I right?
The observed peak shift depends primarily on the chemical bond (e.g., oxide, carbide, boride, etc.), and secondarily on the valence and/or coordination. These papers should be read carefully:

Here's a topic that discusses the application of Bastin's area peak factors:
