The first non-centrosymmetric heavy fermion superconductor CePt$_3$Si [1], crystallizing with CePt$_3$B -type, without an inversion symmetry (one of the key symmetries for Cooper pairing) shows a number of novel physical properties. In order to get insight into the pressure dependence of the strong electron correlations in these materials the present paper provides mechanical property data...
Gallium nitride doped with small concentration of manganese (GaxMn1-xN) is one of the most diluted magnetic semiconductors which used for the spintronic applications. In this work, the Ga31Mn1N32 in the zinc-blende (ZB) and rocksalt (RS) structures were investigated. We employed the ab-initio density functional theory (DFT) within the...
The discovery of a two-dimensional electron gas (2DEG) at the LaAlO3/SrTiO3 interface has set a new platform for all-oxide electronics which could potentially exhibit the interplay among charge, spin, orbital, superconductivity, ferromagnetism and ferroelectricity. In this work, by using angle-resolved photoemission spectroscopy and conductivity measurement, we have studied the behavior of...
In microelectronic industry, lithography and patterning by using ions bombard on the surface to remove atoms of material is a very important process. In data storage manufacturing, ion etching process is chosen to prepare a specific pattern under the read-write head of the hard disk drive (HDD) to form an “air bearing surface” or ABS. This makes the HDD head can float or slide over the surface...
Thermoelectric materials have the ability to convert a heat flow into an electrical charge carrier flow (energy flow). TiNiSn-based thermoelectric half-Heusler phases (noncentrosymmetric, cubic MgAgAs-type) have proven to be excellent thermoelectrics. The large-scale production and particularly nanostructuring of materials by preferably system-inherent phases need a profound knowledge not only...
The light shone upon hybrid organic−inorganic perovskite (HOIP) has never been brighter. Many researchers have claimed that this material could hold the key to the new era of photovoltaic technology, owing to its efficiency, both energetically and economically. Despite all its merits, perovskite solar cell is plagued by an indispensable draw back; it degrades precipitously under sunlight. Not...
An efficient membrane for helium separation from natural gas is quite crucial for cryogenic industries. However, most experimentally available membranes fail in separating He from small molecules in natural gas, such as Ne, $H_2$, $O_2$, CO and $N_2$. Recently, a new 2D graphene-like sheet: $C_2$N was synthesized via a simple wet-logical reaction. $C_2$N has more advantage than among other...
