Due to the recent discovery of the room-temperature visible light
emission from porous silicon (P-Si), a great interest in P-Si and
related materials has arisen in the last decade of the 20th
century. Crystalline (c-) Si, at the heart of integrated circuits,
has an indirect band gap of 1.1 eV, which limits its application in
optoelectronics. The visible light emitting P-Si may open a new
field combining Si integrated technology and optoelectronics. This
book is a comprehensive review of the recent research and
development of porous silicon. Strong visible photoluminescence
(PL) and electroluminescence (EL) from P-Si and other forms of
silicon nanocrystallites (nc-Si) are reviewed. Several proposed
mechanisms for the PL from porous silicon such as quantum
confinement, amorphicity and molecular PL are studied. The
following issues are covered: mechanisms for the visible light
emission, physical structures, studies of the PL and EL,
correlation of structure and optical studies, surface physics and
chemistry, relationships among various forms (P-Si, a-Si, c-Si),
device applications, future developments.
