Materials used for cooled infrared detection include photodetectors based on a wide range of narrow gap semiconductors including: 1  indium antimonide (3-5 Î¼m) 2  indium arsenide. 3  mercury cadmium telluride (MCT) (1-2 Î¼m, 3-5 Î¼m, 8-12 Î¼m) 4  lead sulfide. 5  lead selenide.
The first half, which I did not like, focuses upon Benjamin Franklin's early years - his amorous relationships first with his later to be wife (Deborah) and then the mother (Anne) of his first child (William), who was born out of wedlock. The actual name of the woman who was the mother of his son William is not known.
But I only know of 3. An illegitimate son, William, born prior to his union with Deborah. His children with Deborah were-a son Francis Folger, known as Franky, born in October 1732, died at 4 years, and a daughter, Sarah, but called Sally, born in 1743.
