Introduction and
Acknowledgment
PISCES-2ET is a dual energy transport (for carrier temperatures and lattice thermal diffusion) version
of PISCES-II developed based on Stanford’s 9009 version and Intel’s enhanced 8830 version. This
work is completed under the support of SRC (Semiconductor Research Corp.), ARO (Army Research
Office), and ARPA (Advanced Research Projects Agency) and with close collaboration from Intel and
HP. There are many new features available in the 2ET version, predominately, the capabilities to
simulate the carrier and lattice temperatures and heterostructures in compound semiconductors. Hence,
various non-stationary phenomena such as hot carrier effects and velocity overshoot can be analyzed
using this program. The electrical behavior of optoelectronic devices can also be simulated with
reasonable accuracy. Most of the material parameters have been calibrated and thoroughly surveyed
with the help from industry. Other new features which can be found in PISCES-2ET include:
• High and zero frequency small signal AC analysis
• Improved initial guess using Newton projection method
• Carrier energy dependent mobility and impact ionization models
• About ten different local and non-local (electric) field dependent mobility models
• Parameterization of array sizes for expansion of maximum grid number
• ASCII and binary exchange data format with process simulation programs
