Dear members, Could anyone recommend a supplier for prescribed porous silicon chips ? We need the pores to be at prescribed characteristic length (tens of microns) and volume ratio in the chip. As requested by the list administrator, please reply to me and not to the entire list. Thank you in advance, Danny Klein. _______________________________________ Danny Klein Department of Mechanical Engineering Technion - Israel Institute of Technology Haifa, 32000 Israel Email: dannykl@tx.technion.ac.il Office(Lab) telephone : 972-(4)-8292946(3861)
