Supplier: ASTM International
Description: recombination lifetime as determined with low-injection level (4) is discussed in Appendix X2. The identity and density of impurity centers found to be present in the wafer by means of recombination lifetime measurements may usually be determined more reliably from deep-level

that they alter the input voltage to give a constant output. They regulate that output in a continual way, changing it slightly to maintain the output at a certain level. If the input voltage changes or the load shifts, the regulator will adjust to keep the voltage steady. This is crucial for stable (read more)

Deep Level Transient Spectroscopy Using HF2LI Lock-in Amplifier
A very small concentration of lattice point defects, or simply defects, such as vacancies, impurities, dislocations, grain boundaries or cavities, are responsible for creating many different properties in semiconductors. Defects play a crucial (either beneficial or detrimental) role in determining

Gated Data Transfer for Increased Data Sampling Rate on the MFIA and MFLI
For measurements of signals which are rapidly changing, for example, when measuring capacitance transients in Deep Level Transient Spectroscopy (DLTS), high temporal resolution is required. In its standard operating configuration, the MFIA (or MFLI with MF-IA option) can sample and transfer
