Silicon Near-Infrared Sensor Using Trench Photodiode Array

open access: yesIEEE Access, 2021
In this paper, we report a method of increasing the sensitivity of a silicon near-infrared sensor. The sensor is realized by forming multiple trench-type photodiodes in a silicon chip. The trench photodiodes can be formed using conventional semiconductor

On the energetic origin of self-limiting trenches formed around Ge/Si quantum dots

open access: yes, 2004
At high growth temperatures, the misfit strain at the boundary of Ge quantum dots on Si(001) is relieved by formation of trenches around the base of the islands.

Parent‐to‐Child Information Disclosure in Pediatric Oncology

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Despite professional consensus regarding the importance of open communication with pediatric cancer patients about their disease, actual practice patterns of disclosure are understudied. Extant literature suggests a significant proportion of children are not told about their diagnosis/prognosis, which is purported to negatively ...

Microplastics and synthetic particles ingested by deep-sea amphipods in six of the deepest marine ecosystems on Earth [PDF]

open access: yesRoyal Society Open Science, 2019
While there is now an established recognition of microplastic pollution in the oceans, and the detrimental effects this may have on marine animals, the ocean depth at which such contamination is ingested by organisms has still not been established. Here,
