Why we recommend using SimuLED in education

SimuLED software package allows one to simulate and visualize processes inside LEDs and LDs from internal quantum efficiency of heterostructure to light extraction form the die. It is fast and easy to learn. We recommend it as an educational tool for under- and postgraduate students, because using SimuLED students can:

• Get results of numerous experiments when time is pressing
• Learn to integrate computations into their work
• Supplement their thesis with computation results
• Get a feel of how stuff works

We have included into the package a number of pre-set examples, that can serve as a convenient basis for the course.

Examples supplied with SiLENSe module:

Many of the examples and case studies listed below can be downloaded from http://downloads.str-soft.com/

• Example 1 Blue SQW LED heterostructure
• Example 2 Blue MQW LED heterostructure
• Example 3 UV Laser Diode on sapphire substrate
• Example 4 AlGaAs Laser Diode
• Example 5 Hybrid II-O/III-N LED (ZnO-based LED)
• Example 6 Polar/Semipolar/Nonpolar Heterostructures

Examples and case studies for SpeCLED & RATRO:

Many of the examples and case studies listed below can be downloaded from http://downloads.str-soft.com/

• Example 1 - Coupled computation of current spreading and heat transfer in a planar die 1
• Example 2 - Isothermal computation of current spreading in a planar die 2
• Example 3 - Isothermal computation  of current spreading in a planar die 2 with a spreading layer
• Example 4 - Coupled computation of current spreading  and heat transfer in a planar die 2
• Example 5 - Coupled computation of current  spreading and heat transfer in a planar die 2 with a spreading layer
• Example 6 - Coupled computation of current spreading  and heat transfer in a vertical die 1 without a blocking layer
• Example 7 - Coupled computation of current spreading and heat transfer in a vertical die 1 with a blocking layer

“Flight simulator” for future device engineers

SimuLED is also an excellent tool for training future device engineers:

• Test the performance of your heterostructure
• Design contact configuration and
• See how LED or LD will work

One can do all of the above fast and without any waist of materials or equipment amortization.

SimuLED can be used for research

While here we mostly promote SimuLED for education, it can also be used to conduct research. It is currently used by a number of research university groups. It is also used in R&D departments to generate intellectual property for further industrial use, as it allows to try out design ideas, to test proposed heterostructures, to see how ones ideas would work when implemented.

Examples of research work conducted using SimuLED:

Also, see the presentation by professor Hiroshi Amano (Meijo University) at 28th Electronic Materials Symposium: 2009.07.08 28th EMS Amano.pdf

One more example: at ICNS-2007 two research groups reported on the role of the Auger recombination in IQE droop. STR predicted it theoretically using SimuLED and Lumileds showed it experimentally.

We know needs and wants of universities firsthand

STR works with educational and research institutions on a daily basis. Several of our team members teach at universities. We also support several local universities and research institutions by providing grounds and software for their under- and post-graduate students to conduct research in the field of numerical simulation. Based on this work, numerous masters and several doctorate works have been successfully completed.

In some cases, SimuLED can be customized to meet the needs of your particular research or educational program.

Finally, universities get substantial discounts on both single and department license.
