William Jensen reports, below, that Grimm and Dehlinger developed an early form of tetrahedron in the nineteen twenties/thirties, however, this knowledge appears to have been forgotten. The Grimm Tetrahedron symbolically shows the four main types of bonding in solid chemical compounds: metallic (...
Asymmetric transport characteristic inn- andp-type conductivity has long been a fundamental difficulty in wide bandgap semiconductors. Hexagonal boron nitride (h-BN) can achievep-type conduction, however, then-type conductivity still remains unavailable. Here, we demonstrate a concept of orbital split ...
We have studied the Mg doping of cubic GaN grown by plasma-assisted Molecular Beam Epitaxy (PA-MBE) over GaAs (001) substrates. In particular, we concentrated on conditions to obtain heavy p-type doping to achieve low resistance films which can be used in bipolar devices. We simulated the ...
What would be the chemical formula for Lithium Oxide? What element was first discovered in the spectrum of the sun before it was discovered on earth? What property of water makes it an effective coolant? What is the type of biasing required for transistor to conduct?
How do the electrons help in predicting the chemical properties of elements? When a compound is separated, is this a chemical change because there are now different elements? Is this an accurate definition of chemical bonding: 'a pr...
Schottky-type sensors typically comprise a metal in contact with a semiconductor material (MS) or a metal in contact with a thin insulating (generally an oxide) layer on a semiconductor material (MIS/MOS). From: Sensors and Actuators B: Chemical, 2011 ...
The H-insertion induces interesting magnetic transitions governed by two effects: the increase of the unit cell volume linked to the H-absorption and the occurrence of the RE-H chemical bonding. Some typical examples are reported in this present brief review....
Importance of heat storage materials has recently been increasing. Although various types of heat storage materials have been reported to date, there are few well-balanced energy storage materials in terms of long lifetime, reversibility, energy density,
(no shift) and Ni-incorporation (significant shift to lower wavenumber) along with their comparable influence on the position of sulfate bands allow to deduce the chemical composition of kieserite in a ternary Mg–Mn–Ni system based on spectroscopic remote sensing or in situ data from celestial...
