Si-MoS Vertical Heterojunction for a Photodetector with High Responsivity and Low Noise Equivalent Power.

In this study, we propose the fabrication of a photodetector based on the heterostructure of p-type Si and n-type MoS. Mechanically exfoliated MoS flakes are transferred onto a Si layer; the resulting Si-MoS p-n photodiode shows excellent performance with a responsivity ( R) and detectivity ( D*) of 76.1 A/W and 10 Jones, respectively.

Marker chromosomes in Korean patients: incidence, identification and diagnostic approach.

The identification of marker chromosomes is important for genetic counseling. However, the origin or composition can rarely be defined with conventional cytogenetic technique alone. In this study, we investigated the incidences and types of marker chromosomes in Korean patients and attempted to establish a cost-effective diagnostic approach for marker chromosomes.
