A Review of the CMOS Buried Double Junction (BDJ) Photodetector and its Applications

A CMOS Buried Double Junction PN (BDJ) photodetector consists of two vertically-stacked photodiodes. It can be operated as a photodiode with improved performance and wavelength-sensitive response. This paper presents a review of this device and its applications. The CMOS implementation and operating principle are firstly described. This includes the description of several key aspects directly r...

Ten Years on

The careers of doctors qualifying in the United Kingdom ?ver the decade 1974 to 1983 are being studied by a Qroup now based in Oxford (1). As part of the study, the doctors who graduated from Bristol in 1976 were surveyed about career preferences during their preregistration year (2), but unlike those qualifying in 1974, 1977, 1980 and 1983 they are not being followed to assess career progress....

Mendel, 150 years on.

Mendel's paper 'Versuche über Pflanzen-Hybriden' is the best known in a series of studies published in the late 18th and 19th centuries that built our understanding of the mechanism of inheritance. Mendel investigated the segregation of seven gene characters of pea (Pisum sativum), of which four have been identified. Here, we review what is known about the molecular nature of these genes, which...
