Updated on 03-19-2012

- The lab notebook is due the last day of the final-exam week

- Please place it in SB1-201 (on the table at you left, righ after entering the lab).
- If you preferred more privacy on you lab notebook, leave it in SB1 Room 30.
- Please, DO NOT leave you notebook in my mailbox (Physics Office).

-  On the table you will find also the evaluation sheets. Please fill out one and place
    it in the blue envelope.

Text         No textbook is required at this time. Still, due to the variety of experiments to be covered, students may have to consult
                  a variety of books on electronics available in the PSU library. Alternatively, if you decided to buy a book I would suggest:
                            "Foundations of Electronics," by J.R. Cogdell, Prentice Hall
                            "Foundations of Electric Circuits," by J.R. Cogdell
                            “The Art of Electronics,” by Horowitz & Hill; 2nd Ed., Cambridge University Press
                            “Basic Electronics for Scientists,” James Brophy, McGraw-Hill.
                  Laboratory notes will be available online.

Grading:    Lab notebook                                                                   35% 
                 All the experiments, except the three write-ups (see below) must be included in the lab notebook.
                 Reason for keeping a lab-notebook: It helps develop skills for reporting scientific results.
                 Good presentation is expected: clear, readable, neat.
                 Each experiment description should be broken down into sections:
                           Abstract,
                           List of equipment used,
                           Procedure,
                           Graphs,
                           Data Analysis, and
                           Conclusions.
                 Lab notebooks will be randomly revised on a weekly basis.
                
                 A quiz is taken during the last two weeks on an individual basis, which includes basic questions related to the experiments
                 performed in the previous weeks. For this reason, keep your lab notebook well organized and updated as to have
                 information quite handy at any time.

                 Work performance during laboratory session                30%
                  Keep your lab station clean, free of dust.
                 Good record attendance during official time meeting.
                 Positive attitude to complete tasks.
                 Follow guideline to prevent equipment damage (i. e. make sure power supplies are in its lowest output values before turning
                 them on.)
                 Estimate the precision of the equipment used.

                 Report write-ups                                                           35%
                 Out of the 10 experiments listed below, we will require write-up papers, journal quality of 3 selected experiments: 03, 05 and 08.
                 They are due the week after the experiment is officially scheduled.

                             Notes on PN JUNCTIONS  The main objectives in these notes is to understand a) the concept of chemical potential,
                                       and b)  the relationship between the voltage across the pn junction and the width of the depletion
                                        layer. This concept will allow us to inderstand better the  functioning of the Filed Effect Transistors in their
                                       different modalities.

                      starting from simple logic devices (flip flops), computer memories (ROM, RAM) and now programmable hardware devices
