The phrase "a shallow donor" is correct and usable in written English.
It can be used to describe someone who contributes or donates in a superficial or insincere manner, often without a deep commitment or understanding of the cause.
Example: "While he claims to support the charity, his actions suggest he is just a shallow donor, only interested in the publicity."
Alternatives: "a superficial contributor" or "a cursory supporter".
The increasing interstitial zinc acts as a shallow donor.
An investigation of likely donor impurities reveals that hydrogen acts as a shallow donor.
However, first-principles calculations showed that oxygen vacancies are not a shallow donor but rather a deep level [29].
By means of first-principle electronic structure calculations, we show that NH3 is a shallow donor regardless of the growth orientation of the SiNWs.
A shallow donor impurity corresponding to an excitonic peak at approximately 3.363 eV has been correlated to hydrogen impurity by many authors, see for example [29].
This paper treats theoretically the angle dependence of the ground state binding energy of a shallow donor impurity in semiconductor quantum-well systems on the tilted magnetic field.
It can conclude that with the assistance of B, S is a suitable shallow donor impurity in diamond.
In an interesting paper, Lany et al. [32] have shown using first-principal electronic structure calculations that the anion vacancies in II VI semiconductors as a class of intrinsic defects exhibiting metastable behavior and have predicted that PPC is caused by the oxygen vacancy VO in ZnO, originating from a metastable shallow donor state.
Substitutional hydrogen at the oxygen site, from many experimental and theoretical investigations, is believed to be an important shallow donor in ZnO [23, 28].
Moreover, this study found that the ammonium (NH4) had strong interactions with graphene, forming a strong bond that introduces a large amount of shallow donor states into the system.
In this paper this analogy is applied for the investigation of binding energy of hydrogenlike shallow donor in a thin size-quantized wire of the InSb/GaAs semiconductors in a magnetic field, parallel to the wire axis.
