Abstract

LabVIEW is a software development platform
that can be programmed with a graphical interface and so, measurement and
instrumentation problems are used to deliver a solution. In the sensor
applications, it is very important to calculate the main electronic parameters
of the produced samples and it takes a lot of time to calculate these
parameters and evaluate results. Therefore, LabVIEW based a software system was
developed to minimize the time spent. In this way, it was used to make the
analysis as fast as possible. This study aimed to calculate quickly the
obtained results from the measurement system. For this purpose, AuPd/n-GaAs
Schottky Junction Structure (SJS) was produced by using RF and DC sputtering
techniques to investigate on electronic parameters of SJS. The forward and
reverse current-voltage (I-V) of SJS at ±3V were measured at room temperature
(295 K). By using thermionic emission (TE) theory, Ohm’s law, Cheung and
Cheung’s function and modified Norde’s function, the electronics parameters
such as the series resistance (R_s), the shunt resistance (R_sh),
the barrier height (Φ_B0) and the ideality factor (n) were calculated
and graphics, which were drawn according to these models, via the developed software
platform.
