Nanotechnology is defined as the branch of science dealing with extremely small-sized
particles with a size in the range of 1–100 nm, which are termed nanoparticles. Due to the …

In the last ten to fifteen years there has been much research in using amorphous and
polycrystalline semiconductors as x-ray photoconductors in various x-ray image sensor …

Abstract In this work,(2¯ 01) oriented β-Ga 2 O 3 thin films have been grown on p-type
silicon (100) substrates by laser molecular beam epitaxy. β-Ga 2 O 3/Si p–n heterojunctions …

Amorphous selenium (a-Se) is a photoconductive material that has been intensively
investigated from its early application in xerography to its present application in flat panel X …

We describe the progress in the science and technology of stabilized a‐Se from its early use
in xerography and xeroradiography to its present use in commercial modern flat panel X‐ray …

Phase-change materials are successfully employed in optical data storage and are
becoming a promising candidate for future electronic storage applications. Despite the …

Elemental selenium (Se), as the oldest photovoltaic material, has many advantages such as
a direct fundamental band gap, earth-abundance, simple composition, nontoxicity, and a low …

The threshold switching effect of phase change memory devices is typically parameterized
by the threshold voltage at which this breakdown occurs. Using phase change memory …

An ovonic threshold switch (OTS) based on chalcogenide glasses finds application as a
selecting device in storage class memory (SCM) arrays. The OTS operation relies on the …

Phase-change random access memory (PRAM) technology is reviewed. PRAM uses the
phase change between the amorphous state and the crystalline state caused by Joule …
