No full textOn the Multi-parallel Diodes Model in Au/PVA/n-GaAs Schottky Diodes and Investigation of Conduction Mechanisms (CMs) in a Temperature Range of 80-360 K
No full textAu/PVA/n-GaAs (MPS) type Schottky diodes (SDs) were fabricated and
investigated in a temperature range of 80-360 K to explain their
possible conduction mechanisms (CMs). Three distinct linear regions with
different slopes were observed in ln(I)-Vplots. The first region (R1),
is within the range of 0.22-0.60 V, the second region (R2), is within
the range of 0.64-0.90 V, and the third region (R3), is within the range
of 1.1-1.5 V. It was shown that both ideality factor (n) and zero-bias
barrier height (phi(Bo)) are strong functions of temperature for all
three regions. It was noticed thatnvalues decreased and phi(Bo)values
increased with increasing temperature. In order to ascertain the
possible CMs, phi(Bo) - n, - phi(Bo) - q/2kT, and (n(-1) - 1) -
q/2kTplots were also examined. In each of these plots, two linear
regions were obtained within each of the three regions. The region from
80-180 K is called the low-temperature range (LTR), and the region from
200-360 K is called the high-temperature range (HTR). It has been
revealed that the reason for the deviation from the classical thermionic
emission (TE) theory cannot be explained only by the existence of the
interface layer, interface states (N-SS) or quantum mechanical tunneling
mechanisms, which can be also explained by the double Gaussian
distribution (DGD) due to barrier inhomogeneity. Finally, the
experimental Richardson constants (A{*}) were calculated from the
interception point of the modified Richardson curve in LTR and HTR for
all three regions. It was calculated as 6.22 and 8.13 A/cm(2)K(2)for RI,
7.77 and 8.14 A/cm(2)K(2)at R2, and 7.07 and 8.13 A/cm(2)K(2)at R3 for
low- and high-temperature ranges, respectively. It is clear that
especially HTR results are quite close to the known theoreticalA{*}
value of 8.16 A/cm(2)K(2)for n-GaAs

No full textAn adaptation of pseudo-score confidence interval method for linear mixed models
No full textWe adapt a confidence interval method based on a generalized Chi-Square
test for fixed effect parameters of linear mixed models. Under different
correlation structure of a response variable of a linear mixed model,
the performances of the adaptation method pseudo-score and some of the
existing confidence interval methods are investigated by carrying out a
Monte Carlo simulation study. The simulation study suggests that
pseudo-score method provides better results for small to moderate sample
size cases with dependent observations in terms of coverage probability
rates and average expected lengths. A depression study is analyzed for
demonstrating the adaptation method
