A Theoretical Analysis of the Frequency Response in p-i-n Photodiodes that Use InGaAs/InP Materials
MicromachinesThis investigation is centered on the analysis of frequency response characteristics of a p-i-n photodiode using InxGa1−xAs/InP. The InGaAs/InP can be developed under three conditions: compression, tensile strain, and lattice matching.

Journal of Nanoscience and Nanotechnology, 2002 The current review article attempts to cover the field of nanoporous materials, thereby materials with voids of the order of 1 nm to 100 nm or even larger. Concepts, that have an effect on a more general basis, are introduced and the common features among the different classes of nanoporous materials are demonstrated enabling understanding their ...

Materialism against Materialism [PDF]
, 2021 This text proposes to overcome the wide-spread error of dismissing Marx’s critique of all materialism before him as being reductionist and therefore philosophically and scientifically unacceptable. Instead, it attempts to create a non-reductionist understanding and practice of materialism in philosophy — especially by referring to key contributions by ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background While Wilms tumor (WT) typically has a favorable prognosis, relapsed cases—especially those with high‐risk histology—remain therapeutically challenging after intensive frontline therapy. The combination of vincristine and irinotecan has demonstrated activity in pediatric solid tumors, and pazopanib, a multi‐targeted tyrosine kinase ...
