We present in this paper an analytical model of the current voltage (I-V) characteristics for submicron GaAs MESFET transistors. This model takes account the analysis of the charge distribution in the active region and incorporate a field depended electron mobility, velocity saturation and charge build-up in the channel.we propose In this framework an algorithm of simulation based on mathematical expressions obtained previously. The results obtained of the model are discussed and compared with those of the experimental data reading obtained from the literature [I], The agreement has been shown to be good.


Effects of Array Dimensions on the Resonance Characteristics of SRR Type Metamaterial Arrays with Small Sizes: Simulations and Experiments
Ekmekci, E.; Topalli, K.; Akın, Tayfun; Sayan, Gönül (2009-08-21)
It has been discussed in various studies that two dimensional periodical arrays of SRRs with large array sizes have wider stop bandwidths and lower transmission magnitudes around their resonance frequencies as compared to the single SRR unit cell. In this paper, effects of array dimensions on the transmission characteristics of SRR arrays are investigated in more detail especially for small sized arrays in a comparative manner. For this purpose, various SRR arrays with small array sizes are fabricated and t...
Effect of Feed Composition on the Gas Separation Performance of Binary and Ternary Mixed Matrix Membranes
Sen, Deger; Yılmaz, Levent; Kalıpçılar, Halil (Informa UK Limited, 2013-03-01)
Binary and ternary component mixed matrix membranes comprised of zeolite 4A and p-nitroaniline (pNA) in the polycarbonate (PC) matrix were prepared and appraised in gas separation. For comparison, homogenous membranes of PC and PC/pNA membranes were also investigated. The membranes were utilized to separate binary mixtures of CO2/CH4, H2/CH4, and CO2/N2. The effect of feed composition on the separation performance of membranes was investigated. Separation factors and ideal selectivities were similar for the...
Effect of amorphous SiC layer on electrical and optical properties of Al/a-SiC/c-Si Schottky diode for optoelectronic applications
Barbouche, M.; Benabderrahmane Zaghouani, R.; Ben Ammar, N.E.; Aglieri, V.; Nasser, H.; Turan, Raşit; Ezzaouia, H. (2021-01-01)
In this work, we report on the study of the electrical and optical properties of amorphous silicon carbide (a-SiC)-based Schottky diodes for optoelectronic applications. A significant decrease of reflectivity and an enhancement of the passivating properties of more than 97% were reached after a-SiC layer deposition on silicon substrate. The deposited a-SiC film exhibits a dielectric constant of 2.143. Temperature effect on Schottky diode performances was carried out through the analysis of the current–volta...
Analysis and Elimination of the Capacitive Feedthrough Current on Electrostatically Actuated and Sensed Resonance-Based MEMS Sensors
Kangul, Mustafa; Aydin, Eren; Gokce, Furkan; Zorlu, Ozge; Külah, Haluk (2017-12-01)
This paper presents the investigation of two different capacitive feedthrough current elimination methods with an analysis of the effect of the capacitive feedthrough current on the resonance characteristics of electrostatically actuated and sensed resonant MEMS sensors. Electrostatically actuated and sensed resonators have various applications, such as accelerometers, gyroscopes, mass sensors, and temperature sensors. In most of these applications, as sensitivity increases, gain decreases. The capacitive f...
Effect of Presoaked Expanded Perlite Aggregate on the Dimensional Stability and Mechanical Properties of Engineered Cementitious Composites
KESKİN, SÜLEYMAN BAHADIR; Sulaiman, Kamaran; Sahmaran, Mustafa; Yaman, İsmail Özgür (American Society of Civil Engineers (ASCE), 2013-06-01)
This paper reports on an investigation of the use of expanded perlite aggregate as saturated lightweight aggregate (LWA) with respect to the mechanical and dimensional stability properties of engineered cemetitious composites (ECC). Expanded perlite aggregate was soaked in water for 24 h before its use in ECC, and replaced 10, 20, and 30% of the aggregate that was used in ECC production. The mixture proportion of a standard ECC mixture with properties that have been extensively reported in the literature is...
