    The document contains data from four experiments measuring the I-V characteristics of semiconductor devices: 1) A pn junction diode shows forward bias characteristics with increasing voltage and current until saturation. 2) Measurements of a Zener diode show little to no current until the breakdown voltage is reached, after which the voltage remains constant while current increases with applied voltage. 3) An LED begins emitting light and increasing current above its threshold voltage of around 2V, with voltage remaining nearly constant as current rises with more applied voltage. 4) No reverse bias measurements are included for the pn junction diode.
