Process or Environmental Factors<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>High-temperature contamination<\/strong>: In high-temperature processes (such as diffusion or annealing), quartz tubes may release impurities or react with process gases (such as O\u2082, H\u2082), contaminating wafers or samples.<\/li>\n\n\n\n<li><strong>Surface contamination<\/strong>: Inadequate cleaning of quartz tubes (residual particles, organic matter) or improper storage (exposure to dust, moisture) can introduce surface recombination centers.<\/li>\n\n\n\n<li><strong>Thermal stress damage<\/strong>: Rapid heating and cooling can cause microcracks in quartz tubes. Internal stress regions may become active sites for carrier recombination.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">3. Testing and Usage Condition Issues<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Mismatch in process parameters<\/strong>: For example, if the temperature exceeds the quartz tube\u2019s tolerance (ordinary quartz tubes may crystallize above 1200\u00b0C) or if the gas environment corrodes the tube wall (such as Cl\u2082, HF).<\/li>\n\n\n\n<li><strong>Measurement errors<\/strong>: Carrier lifetime testing methods (such as microwave photoconductive decay \u03bc-PCD and quasi-steady-state photoconductance QSSPC) are affected by sample surface condition, light intensity, and other factors, so testing interference must be eliminated.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">4. Potential Problems from Other Suppliers<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Deviation in custom specifications<\/strong>: If quartz tube dimensions (such as uneven wall thickness) or coatings (such as anti-reflective coatings) are not optimized to customer requirements, they may cause uneven heat distribution or local defects.<\/li>\n\n\n\n<li><strong>False labeling of parameters<\/strong>: Some suppliers may falsely claim purity levels (e.g., labeling as \u201chigh purity\u201d but actually not reaching 99.99% SiO\u2082) or fail to disclose hydroxyl content (which affects UV transmittance).<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Technical Solutions<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Recommend using <strong>low-hydroxyl synthetic quartz tubes<\/strong> to reduce UV absorption and impurity recombination centers.<\/li>\n\n\n\n<li>Offer <strong>custom quartz tube pre-treatment services<\/strong> (such as high-temperature annealing and etching cleaning) to eliminate surface contamination.<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<p>Carrier lifetime reduction can involve multiple factors, especially in quartz tube application scenarios such as semiconductors, photovoltaics, or high-temperature processes.
