Observation; On rare occasions (if you look hard enough behind the curtain), we occasionally run across a tid-bit of info concerning the current roadblocks in state-of-the-art nano-research...for QDots in our case. Across the tech sector, we are typically given privy to positive info that serves their purpose, but are rarely shown the flipside. I-for-one think (as an informed investor) that a better understanding of these factors helps promote a degree of patience (on our part) while they sort-out these problems...divulging this info need-not be regarded as a negative. We, as investors, are part of this process, & as adults, can & should not only be privy to the positives, but the details of what is yet to be resolved. So, when frustration sets-in after a lengthy wait in the dark...as it often does...& you find yourself asking 'what's the hang-up, for christ-sakes' , explanations (like the forgoing) go a long way in that regard. This shows that it's possible to let us in on the big picture without giving away the farm. This example provides a laymens understanding of what the hang-up is for QDot transistors, industry-wide.
"A number of studies have used quantum dots to produce the similar effects but because the dots are much larger and not uniform in size, due to the nature of their synthesis, the results have not been reproducible—not every device made with quantum dots behaved the same way."

OK, that wasn't so hard, was it[?]...I didn't just find my self falling to the floor in agony after reading that...on the contrary, I take some comfort in-the-knowing......just spit it out, we can handle it
