The distinction between "physical" and "equivalent" noise sources in bipolar junction transistors and other semiconductor devices has become blurred in the current engineering textbooks. An unfortunate consequence of this is the emergence in the literature of fictitious noise sources such as the "the collector-current shot noise" and the "base-current shot noise". These are often assigned a physical reality and incorrectly treated as real physical noise sources, independent of circuit topology. Text-books have encouraged successive generations of students in this belief. Non-physical noise sources such as these are convenient and legitimate, even essential, for the effective modeling and simulation of circuit noise. However their naïve use in teaching and research is likely to continue to give rise to fallacious concepts and misleading conclusions. The physical. The physical modeling of the light-emitting diode, the photon transport transistor and the bipolar junction transistor are briefly discussed to illustrate this view.

The Boltzmann transport equation (BTE) for multiple bands is solved by the spherical harmonic approach. The distribution function is obtained for energies greater than 3 eV. The BTE is solved self consistently with the Poisson equation for a one dimensional npn bipolar junction transistor (BJT). The novel features are: the use of boundary fitted curvilinear grid, and Scharfetter Gummel type discretization of the BTE.

The last two decades have witnessed a plethora of novel biomaterials that work significantly in the discovery of drugs and the point check of drugs, Biosensors. PLGA (Poly-(L-Lactide-co-glycolic Acid)), has already been shown to be a substrate for manufacture of substrates for OFETs, that in the future would be the forefront of electroceuticals. But, Polylactic Acid (PLA) derived and pegylated nanoparticles generated scaffolds, promote neural self-differentiation, nanowires derived from Polythiophene (PTs) can be utilised in the area of biosensors. Similarly, PT derived PEDOT:PSS(poly (3,4-ethylenedioxythiophene) poly (styrenesulfonate) polymer doped with appropriate cations is useful to manipulate directly the biological response of cells on the same grounds, organic electrochemical transistors (OECTs) based on PEDOTPSS coupled with bilayer lipid membranes (BLMs) were shown to act as ion-to-electron converters. A solid-state ion bipolar junction transistor (IBJT) has been developed to serve as a circuit element for neurotransmitter signal delivery. Consequently, the traditional drug discovery methods have far gone by. This era demands a much more modified and multiple disciplined methods for modern drug discovery. This review gives an insight and instance of this paradigm.
