Which article are you evaluating?
Semiconductor

Why you have chosen this article to evaluate?
I chose this article because I find the properties of semiconductors to be extremely fascinating in terms of electron-hole pairs and how the process of electron-hole annihilation effects the gain and lasing ability of diode lasers.

Evaluate the article
The article overall is very well written with a neutral and balanced tone and none of the sections being portrayed as more important than the rest. The light emission section doesn't include a quick mention of the process by which the electrons relax from excitation and produce light, which is called electroluminescence. I do believe this article could benefit from a picture of a crystal lattice showing an excess of electrons or a lack of electrons for doped materials. It would help the reader understand what the article means by donors and acceptors by showing the regions that are missing an electron or the regions with an excess of electrons and how those electrons/holes can move around. A gif from a simulation would be even better.
