Abstract:

This thesis aims at shedding light on the microscopic origin of a phenomenon in the field of semiconductor nanostructures, which occurs in transport through a short and narrow quasi one-dimensional constriction, the quantum point contact (QPC). Unlike the stepwise increase of linear conductance of a QPC as function of its width in units of the quantum GQ, which is well understood and was predicted already in the 1950s, an additional shoulder-like step at 0.7xG_Q raises questions since its discovery in 1996 : the 0.7 anomaly. Subsequent experimental investigations revealed a plethora of accompa

Abstract:

Production of asymmetric ceramic membranes intended for oxygen gas separation was done by producing porous supports made from coarse La(0.2)Sr(0.8)Fe(0.8)Al(0.2)O(3-d) powder produced by the solid state reaction method. The porous support was made by adding 40 vol% carbon black as a pore former to a slip which was tape casted. The tape casted green body was dip-coated with a solution of nano-sized La(0.2)Sr(0.8)Fe(0.8)Al(0.2)O(3-d) particles produced by spray pyrolysis, and fired. The asymmetric membranes produced during this work was not gas tight, and thus not viable to use for oxygen gas se

Abstract:

A Quantum point contact (QPC) is a one dimensional constriction, separating two extended electron systems allowing transport between them only though a short and narrow channel. The linear conductance of QPCs is quantized in units of the conductance quantum G_Q=2e^2/h, where e is the electron charge and h is Planck's constant. Thus the conductance shows a staircase when plotted as a function of gate-voltage which defines the width of the channel. In addition measured curves show a shoulder-like step around 0.7G_Q. In this regime QPCs show anomalous behaviour in quantities like electri

Abstract:

The physical mechanisms that quench star formation, turning blue star-forming galaxies into red quiescent galaxies, remain unclear. In this Letter, we investigate the role of gas supply in suppressing star formation by studying the molecular gas content of post-starburst galaxies. Leveraging the wide area of the Sloan Digital Sky Survey, we identify a sample of massive intermediate-redshift galaxies that have just ended their primary epoch of star formation. We present Atacama Large Millimeter/submillimeter Array CO(2-1) observations of two of these post-starburst galaxies at z similar to 0.7

This system is capable not only of generating rapid temperature scans but maintaining a set point temperature to an accuracy of +/-2 mK in a range of 11 to

The magnetic phases in the complex cobaltates Y1−xSrxCoO3−δ (0.7 ≤ x ≤ 0.95) and Ca3Co2O6 have been investigated by susceptibility, heat capacity, X-ray and neutron scattering techniques. These measurements have shown that the super- structure ordering in the perovskite cobaltate Y1−xSrxCoO3−δ which evolves as a function of temperature heavily influences the ferrimagnetic behaviour of this mate- rial. Neutron scattering has also been used to probe the unusual time and magnetic field dependent behaviour of the spin-chain compound Ca3Co2O6, and to further our understanding of the magnetic phase

Abstract:

Two rates of the insect active ingredient zetacypermethrin (MustangMax) were evaluated for control of summer insect pests on bermudagrass, with application made about one month prior to harvest. Crop was 22 inches tall when treatments were applied and had a dense stand, which also intercepted much of the treatment. Little difference existed between the two rates of zetacypermethrin in this study. Treatments reduced planthopper numbers by slightly over 50% for the first 9 days after application. Reduction of bermudagrass mirid populations was 45% at two days post treatment, but numbers of this

In this work, we utilise a multiplexing technique and statistically investigate the 0.7 anomaly observed on the first three plateaus respectively in 571 QPCs, fitting well the van-Hove model.

The lensed QSO sightlines presented here occur at projected distances of d = 3-15 kpc (or d approximate to 1-2 r(e)) from the lensing galaxies, providing for the first time an opportunity to probe both interstellar gas at r similar to r(e) and circumgalactic gas at larger radii r >> r(e) of these distant quiescent galaxies.

Abstract:

碩士<br>國立臺灣師範大學<br>物理學系<br>95<br>We report the first direct real-space scanning tunneling microscopy (STM) study of NaxCoO2 surface (x = 0.84), as prepared by in-situ cleaving in ultra high vacuum. Two categories of ordering phenomena were discovered. First, three Na ordered patterns of Na0.84CoO2 surface, with p(√7 x √7), p(3 x 3), or p(2√3 x 2√3) unit cells, were resolved. These patterns are ascribed to Na ordering. Second, a new phase of one-dimensional stripe was identified. This stripe phase exists on the surface and in the bulk crystal. We also observed fluctuations of the Na ordered pha

Abstract:

碩士<br>國立臺灣師範大學<br>物理學系<br>95<br>We present the Raman-scattering studies of two single-crystalline thin films NaxCoO2 (x = 0.68 and 0.75) and one single crystal Na0.84CoO2. We observe three different Raman-scattering spectra (α-, β-, and γ-type Raman spectra, containing two, three, and seven Raman phonon modes, respectively) on different areas of freshly cleaved Na0.84CoO2 single crystal. We suggest that α-type spectrum stands for NaxCoO2 (beside x = 0.5), while β- and γ-type spectra are caused by the appearance of Co3O4 rather than the other structures of NaxCoO2. We also find that the presenc

碩士<br>國立交通大學<br>電機工程學系<br>107<br>Nowadays, with the development of silicon technology, the low-power system has become more and more popular in portable consumer electronics, bio-sensing systems, and internet-of-things applications. For these applications, there are three issues: the cost of the components, transmission distance, and battery life. The cost is determined with the number of the off-chip components and the size of each chip. The lower the number of the components and the chip size, the lower the price of the system; transmission distance is determined by the output power of the t

Powder x-ray diffraction patterns indicated that single phase existed in a range of 0.7≦x≦1.0. As determined from the magnetic susceptibility, resistivity and specific heat data, these as-cast polycrystal samples exhibit bulk ferromagnetic ordering below the temperature 9.7 ,9.8 , 10.2, 10.5 ,10.6, 7.3,about 4~5 K and about 4~5 K with x = 1.2, 1.1, 1.0, 0.9, 0.8, 0.7, 0.75 and 0.67, respectively.
