You need a massive amount of thermal energy, and you need it concentrated exactly where it matters. The problem is that energy loves to escape. That&rsquo;s why we stopped messing around with standard reflectors and switched to gold coatings. In this kind of setup, every single watt is precious.</p> <h2 id="why-gold">Why gold?</h2> <p>Most people start with aluminum. It&rsquo;s cheap, but it&rsquo;s a sponge for infrared radiation—it absorbs way too much of the heat you&rsquo;re trying to use. Gold is different. It&rsquo;s incredibly good at bouncing infrared radiation right back toward the wafer. By using a high-purity gold coating, we can push more heat per square centimeter onto the surface. It&rsquo;s a simple change, but it means you hit your synthesis temperatures faster. Plus, your power bill stays lower because you aren&rsquo;t wasting energy heating up the walls of your machine.</p>
