Hydrogen strongly affects the electronic and structural properties of many materials. It can
bind to defects or to other impurities, often eliminating their electrical activity: this effect of
defect passivation is crucial to the performance of many photovoltaic and electronic devices …

A review of the properties of hydrogen in crystalline semiconductors is presented. The
equilibrium lattice positions of the various states of hydrogen are detailed, together with the
reactions of atomic hydrogen with shallow and deep level impurities that passivate their …

We investigated semiconductor characteristics for polymeric carbon nitride as a metal-free
photocatalyst working with visible light and have shown that the efficiency of hydrogen
production by photochemical water reduction can be improved by∼ 1 order of magnitude by …

This monograph arose out of the recognition of the importance of hydrogen in modern
semiconductor technology. Hydrogen is a component of most chemicals used in the
fabrication of electronic and photonic devices, is easily incorporated into semiconductors  …

Hydrogen plays an important role in silicon technology, having a profound effect on a wide
range of properties. Thus, the study of hydrogen in semiconductors has received much
attention from an interdisciplinary assortment of researchers. This sixteen-chapter volume …

Hydrogen is a common impurity in all semiconductors. Although it is sometimes deliberately
introduced, hydrogen often penetrates into the crystal during device processing. It interacts
with broken or weak covalent bonds, such as those found at extended and localized defect …

Under suitable circumstances imperfections in semiconductors can bind electrons (holes)
with a binding energy small compared to the intrinsic energy gap of the host; the
wavefunctions characterising the energy levels of the imperfection are extended over many …

An optimized and general synthetic strategy based on in‐situ iodine modifying of polymeric
graphitic carbon nitride is discussed. The as‐prepared iodine functionalized g‐CN shows
enhanced electronic and optical properties, as well as increased photocatalytic activities in …

Optimiert: Die simultane Modifizierung der Bulk‐, Oberflächen‐und elektronischen Struktur
eines Kohlenstoffnitridpolymers gelang durch direkte Cokondensation von Harnstoff und
Ph4BNa. Mit diesem Verfahren werden bordotierte Kohlenstoffnitridnanoblätter erhalten …

Bottom–up synthesis of graphitic carbon nitride semiconductor catalysts for the
photocatalytic evolution of hydrogen by visible light is achieved through the polymerization
of dicyandiamide with organic monomers bearing cyano groups, amino groups, or both. This …
