Optical intersubband transitions (ISTs) for both in-plane polarization (TE) and normalto-plane polarization (TM) in p-type Si1-xGex/Si multiple quantum wells (MQWs) are investigated using 14-band k⋅p model combined with the envelope-function Fourier expansion method. The results show that the amplitudes of different intersubband transitions for TE and TM polarizations, and the overall absorptio...

One of the purposes of consciousness is to acquire knowledge. The models of this task traditionally assume a division between the known and the knower, a division that leads into doubtful reasoning about some kind of (frequently disguised) homunculus. The current paper tries to avoid such fallacies by viewing the adaptation of the mind as an evolutionary process, a process distinct (but not ind...
