Prof. Alon Hoffman

Professor Alon Hoffman is a full professor at the Schulich faculty of Chemistry at the Technion and also holds the Joseph Szydlowsky Chair in Science

Alon completed his D.Sc. in 1987 at the Technion investigating adsorption processes on single crystal metal alloy surfaces by electron spectroscopy

After several post doc years in the USA and Australia, he joined the Schulich Faculty of Chemistry, Technion in 1992 as a senior lecturer where he become full professor in 2007
During the 2012-2016 he was Dean of the Schulich Faculty of Chemistry

Research Areas

Chemical reactivity and physical properties of diamond surfaces

We have studied the adsorption properties of differently oriented single crystal diamond and polycrystalline diamond surfaces and the relation between surface chemical composition, reconstruction and electronic structure. We investigated the interaction of hydrogen, oxygen and water molecules with diamond surfaces

Interaction of electrons and photons with diamond surfaces

Photon stimulated desorption of H+ and H- from hydrogenated diamond surfaces, both single crystalline and polycrystalline have been investigated using synchrotron radiation. Here we assessed and determined the fundamental physico-chemical processes leading to C-H(ads) bond scission induced by core level ionization

Interaction of low energy ions and metastable species with diamond surfaces

The stability of diamond surfaces under low energy ion irradiation has been studied. We have investigated the transformation of the diamond crystalline structure into amorphous carbon induced by low energy ion irradiation and its effects on the electronic properties of the irradiated surfaces

Nucleation and growth of diamond film

Nucleation of diamond is a critical issue to many different avenues of the field (heteroepitaxy, single-crystalline, nano-crystalline, etc). It is considered to be one of the most studied subjects in the field. In particular, we investigated the process of diamond nucleation by bombardment from energetic species
