HIGHLIGHTS
- who: Xiaomeng Xue from the (UNIVERSITY) have published the article: High-operating-temperature mid-infrared photodetectors via quantum dot gradient homojunction, in the Journal: (JOURNAL)
- what: Taking the advantages of colloidal nanocrystals` solution processability and precise doping control by surface dipoles this work shows a HOT midinfrared photodetector with a QD gradient homojunction. The authors compare high-mobility and low-mobility devices (Fig S3, SI), approving the high mobility would also improve the possibility of diffusing carriers reaching SCR and being collected, where diffusion current would also increase.
- how: Ellipsometry measurement For the . . .
