Crosslight APSYS 2023

APSYS software is a unique tool in advanced simulation of physical models of semiconductor devices. This software performs electrical, optical and thermal analyses of semiconductor devices simultaneously based on finite element (FEM) and finite difference time domain (FDTD) numerical methods in two and three dimensions.

The simulation structure in APSYS software is based on band structure engineering and quantum mechanical effects. Also, this software includes various modules for optical simulation, which has made APSYS attract the attention of many researchers in the simulation of optical devices.

APSYS Applications

This software has very wide applications and can simulate almost all semiconductor devices:

• LED, OLED, and AMOLED light-emitting diodes
• Organic, hybrid, thin-film and multi-junction solar cells
• Photodetectors (PD) and infrared quantum well photodetectors (QWIP)
• Bipolar transistors, HEMT, HBT, MOSFET, and MESFET
• Diode devices and resonant tunneling diodes (RTDs)
• MOS devices with quantum mechanical effects (Quantum-MOS)
• Power-based devices (GaN)
• Electro-absorption modulators

The only limitation of APSYS software is that it does not use the photon rate relationship for modeling laser devices. Therefore, PICS3D software has been designed and provided for this application.

APSYS Capabilities

APSYS software has an extensive library of materials and uses hydrodynamic, optical, drift-diffusion, thermionic diffusion, quantum transport and tunneling, heat transfer, Poole-Frankel, and temperature-dependent simulation models. The simulation of the aforementioned models in this software is performed simultaneously.

It is worth noting that the convergence of numerical simulation in this software has industrial considerations. The data obtained from the simulation with APSYS software is as follows:

• Current versus voltage (IV) characteristics
• Two-dimensional electric potential, electric field, and current distribution
• Two-dimensional distribution of electron and hole concentrations
• Two-dimensional distribution of heat carriers in a hydrodynamic model
• Two-dimensional network temperature distribution for heat transfer model
• Band structure under different bias conditions
• AC small signal analysis in any frequency range
• Extraction of AC parameters such as S and Y parameters
• Quantum well subband structure with capacitance combination model for quantum devices
• Two-dimensional distribution of occupation and concentration of deep traps in semiconductors
• Two-dimensional optical field distribution for photonic devices such as optical sensors
• Spontaneous emission spectra as a function of current for LED and OLED
• All of the above as a function of time (Transient model)
• All of the above in different temperature conditions

Pars Optics Specialized Group has provided APSYS software with scientific guarantee for the research and development of semiconductor optical devices in the following versions.

• APSYS software version 2023
• APSYS software version 2018

: Faculty member, Shahid Beheshti University

I am a faculty member at Shahid Beheshti University. My field of activity is optics and lasers. I have been working with various software since almost 2010. Two of the most important companies in the field of laser device simulation are SILVACO and Crosslight, which do not even provide their trial versions to Iranians. With great effort and by getting a letter from my professor outside of Iran, I managed to get their trial version, which was for two months. After a few years and with the desire to obtain these software, fortunately, I managed to obtain them through the acquaintance of the respected and diligent group of Pars Optics. In addition to providing this opportunity, the responsiveness, follow-up, customer-orientedness, and sense of duty of this group impressed me the most.

Faculty member of Islamic Azad University:

As a researcher in the field of optics and photonics, I have benefited from the scientific services of the Pars Optics Specialized Group over the past 5 years. Services such as: 1) Providing training courses such as LUMERICAL and COMSOL 2) Providing the software needed in this field such as COMSOL, LUMERICAL, SILVACO and APSYS 3) Providing scientific consulting in specialized fields. Wishing success and increasing progress for this group, which has played a significant role in the scientific progress of the country by providing such services to researchers.
