The students created a macroscopic, three-dimensional (3D) model of several properties of the periodic table. They explained in their own words the following terms: atomic radii, ionic radii, first ionization energy, and electronegativity. Lastly, they identified, described, and explained the patterns observed in the 3D periodic tables for the following element properties: atomic radii, ionic radii, first ionization energy, and electronegativity.

The figure depicts the excitation of an electron into the conduction band thus leaving a hole in the valence band. An electron-hole pair is called an exciton, and the natural physical separation between them is called the excitonic Bohr radius and is characteristic of each material. Thus when a semiconducting material approaches a size nearing its Bohr excitonic radius, the exciton is said to be confined within the particle and is called quantum

In order to synthesize our metal complexes, we were able to make both Copper and Ruthenium metals. From this, we combined each metal complex with DMSO by refluxing the compound. The metal complexes were analyzed through their melting point and IR spectroscopy to determine whether the metal bonded to a Sulfur atom or an Oxygen atom of the DMSO. After analyzing the IR spectrum, it was determined that S=O shifted to a lower wavenumber in CuCl2~2DMSO and that S=O shifted to a higher wavenumber in RuCl2~4DMSO.

The result from the IR spectra for Trans-[Bis(inosinato)palladium(II)], and inosine are summarized in Table 2 and 3. It is important to note that Trans-[Bis(inosinato)palladium(II)] compound had an extra carbonyl peak at 1712.21 cm-1 which is from inosine impurity.

and a much lower superconducting transition temperature TC relative to the β phase: ca. 0.015 K vs. 1–4 K; mixing the two phases allows obtaining intermediate TC values. The TC value can also be raised by alloying tungsten with another metal . Such tungsten alloys are sometimes used in low-temperature superconducting circuits.

The Drude model can explain the Thermal Conductivity in metals and Electrical Conductivity of metals.

In the early 1900's a duch physicist by the name of Heike Kammerlingh Onnes (pictured above), discovered superconductivity. Before his discovery, Onnes had spent most of his scientific career studying extreme cold. The first step he took toward superconductivity was on July 10, 1908 when he liquified helium and cooled it to an astonishing 4 K, which is roughly the temperature of the background radiation in open space. Using this liquid helium, Onnes began experimenting with other materials and their properties when subjected to intense cold. In 1911, he began his research on the electrical properties of these same materials. It was known to Onnes that as materials, particularly metals, cooled, they exhibited less and less resistance. Bringing a mercury wire to as close to absolute zero as possible, Onnes observed that as the temperature dropped, so to did the resistance, until 4.2 K was reached. There resistance vanished and current flowed through the wire unhindered. Below is an approximate graph displaying resistance as a function of temperature for the experiment Onnes conducted with mercury:

unusual properties. Long-range pi-conjugation in graphene yields remarkable and unique properties, such as high values of its Young’s modulus (1.0 TPa), large theoretical specific surface area (2630m2 g-1),excellent thermal conductivity (5000 W m-1 K-1), high

With advent of scientific research and technological interest, multiferroic materials have drawn much attention for foundational physics, technological application in possible miniaturization and integration for multifunctional devices (e.g. magnetic field sensors, multiple state memory element, transducers, actuators, broadband magnetic sensors, non-volatile memory elements, oscillators, phase shifters, electric field controlled ferromagnetic resonance devices, switching devices, modulation of amplitudes, filters, waveguides, spin wave generation, energy harvesters, magnetic recording read heads, random access memories, RF resonators, tunable inductors, and ME antennas) [1-11]. The most intriguing characteristic of multiferroic materials

We have now discussed the two extremes in electronic materials; a conductor, and an insulator we will now move to a material that lies in between these two, a semiconductor. The
